NAME

msmtp - An SMTP client

SYNOPSIS

Sendmail mode (default): msmtp [option...] [--] recipient... msmtp [option...] -t [--] [recipient...] Server information mode: msmtp [option...] --serverinfo Remote Message Queue Starting mode: msmtp [option...] --rmqs=host|@domain|#queue

DESCRIPTION

In the default sendmail mode, msmtp reads a mail from standard input and sends it to an SMTP server for delivery. In server information mode, msmtp prints information about an SMTP server. In Remote Message Queue Starting mode, msmtp sends a Remote Message Queue Starting request for a host, domain, or queue to an SMTP server.

EXIT STATUS

The standard sendmail exit status codes are used, as defined in sysexits.h.

OPTIONS

Options override configuration file settings. They are compatible with sendmail where appropriate. General options --version Print version information, including information about the libraries used. --help Print help. -P, --pretend Print the configuration settings that would be used, but do not take further action. An asterisk (`*') will be printed instead of your password. -v, -d, --debug Print lots of debugging information, including the whole conversation with the SMTP server. Be careful with this option: the (potentially dangerous) output will not be sanitized, and your password may get printed in an easily decodable format! Changing the mode of operation -S, --serverinfo Print information about the SMTP server and exit. This includes information about supported features (mail size limit, authentication, TLS, DSN, ...) and about the TLS certificate (if TLS is active). --rmqs=(host|@domain|#queue) Send a Remote Message Queue Starting request for the given host, domain, or queue to the SMTP server and exit. Configuration options -C, --file=filename Use the given file instead of ~/.msmtprc as the user configuration file. -a, --account=account_name Use the given account instead of the account named "default". The settings of this account may be changed with command line options. This option cannot be used together with the --host option. --host=hostname Use this SMTP server with settings from the command line; do not use any configuration file data. This option cannot be used together with the --account option. --port=number Set the port number to connect to. See the port command. --timeout=(off|seconds) Set or unset a network timeout, in seconds. See the timeout command. --proxy-host=[IP|hostname] Set or unset a SOCKS proxy to use. See the proxy_host command. --proxy-port=[number] Set or unset a port number for the proxy host. See the proxy_port command. --protocol=(smtp|lmtp) Set the protocol. See the protocol command. --domain=[string] Set the argument of the SMTP EHLO (or LMTP LHLO) command. See the domain command. --auth[=(on|off|method)] Enable or disable authentication and optionally choose the method. See the auth command. --user=[username] Set or unset the user name for authentication. See the user command. --passwordeval=[eval] Evaluate password for authentication. See the passwordeval command. --tls[=(on|off)] Enable or disable TLS/SSL. See the tls command. --tls-starttls[=(on|off)] Enable or disable STARTTLS for TLS. See the tls_starttls command. --tls-trust-file=[file] Set or unset a trust file for TLS. See the tls_trust_file command. --tls-crl-file=[file] Set or unset a certificate revocation list (CRL) file for TLS. See the tls_crl_file command. --tls-fingerprint=[fingerprint] Set ot unset the fingerprint of a trusted TLS certificate. See the tls_fingerprint command. --tls-key-file=[file] Set or unset a key file for TLS. See the tls_key_file command. --tls-cert-file=[file] Set or unset a cert file for TLS. See the tls_cert_file command. --tls-certcheck[=(on|off)] Enable or disable server certificate checks for TLS. See the tls_certcheck command. --tls-min-dh-prime-bits=[bits] Set or unset minimum bit size of the Diffie-Hellman (DH) prime. See the tls_min_dh_prime_bits command. --tls-priorities=[priorities] Set or unset TLS priorities. See the tls_priorities command. Options specific to sendmail mode -f, --from=address Set the envelope-from address. It is only used when auto_from is off. If no account was chosen yet (with --account or --host), this option will choose the first account that has the given envelope-from address (set with the from command). If no such account is found, "default" is used. --auto-from[=(on|off)] Enable or disable automatic envelope-from addresses. The default is off. See the auto_from command. --maildomain=[domain] Set the domain part for the --auto-from address. See the maildomain command. -N, --dsn-notify=(off|cond) Set or unset DSN notification conditions. See the dsn_notify command. -R, --dsn-return=(off|ret) Set or unset the DSN notification amount. See the dsn_return command. Note that hdrs is accepted as an alias for headers to be compatible with sendmail. --add-missing-from-header[=(on|off)] Enable or disable the addition of a missing From header. See the add_missing_from_header command. --add-missing-date-header[=(on|off)] Enable or disable the addition of a missing Date header. See the add_missing_date_header command. --remove-bcc-headers[=(on|off)] Enable or disable the removal of Bcc headers. See the remove_bcc_headers command. -X, --logfile=[file] Set or unset the log file. See the logfile command. --syslog[=(on|off|facility)] Enable or disable syslog logging. See the syslog command. -t, --read-recipients Read recipient addresses from the To, Cc, and Bcc headers of the mail in addition to the recipients given on the command line. If any Resent- headers are present, then the addresses from any Resent-To, Resent-Cc, and Resent- Bcc headers in the first block of Resent- headers are used instead. --read-envelope-from Read the envelope from address from the From header of the mail. Currently this header must be on a single line for this option to work correctly. --aliases=[file] Set or unset an aliases file. See the aliases command. -Fname Msmtp adds a From header to mails that lack it, using the envelope from address. This option allows one to set a full name to be used in that header. -- This marks the end of options. All following arguments will be treated as recipient addresses, even if they start with a `-'. The following options are accepted but ignored for sendmail compatibility: -Btype, -bm, -G, -hN, -i, -L tag, -m, -n, -O option=value, -ox value

USAGE

Normally, a system wide configuration file and/or a user configuration file contain information about which SMTP server to use and how to use it, but all settings can also be configured on the command line. The information about SMTP servers is organized in accounts. Each account describes one SMTP server: host name, authentication settings, TLS settings, and so on. Each configuration file can define multiple accounts. The user can choose which account to use in one of three ways: --account=id Use the given account. Command line settings override configuration file settings. --host=hostname Use only the settings from the command line; do not use any configuration file data. --from=address or --read-envelope-from Choose the first account from the system or user configuration file that has a matching envelope-from address as specified by a from command. This works only when neither --account nor --host is used. If none of the above options is used (or if no account has a matching from command), then the account "default" is used. Msmtp transmits mails unaltered to the SMTP server, with the following exceptions: - The Bcc header(s) will be removed. This behavior can be changed with the remove_bcc_headers command and --remove-bcc-headers option. - A From header will be added if the mail does not have one. This can be changed with the add_missing_from_header command and --add-missing-from-header option. The header will use the envelope from address and optionally a full name set with the -F option. - A Date header will be added if the mail does not have one. This can be changed with the add_missing_date_header command and --add-missing-date-header option. Skip to the EXAMPLES section for a quick start.

CONFIGURATION FILES

If it exists and is readable, a system wide configuration file SYSCONFDIR/msmtprc will be loaded, where SYSCONFDIR depends on your platform. Use --version to find out which directory is used. If it exists and is readable, a user configuration file will be loaded (~/.msmtprc by default, but see --version). Accounts defined in the user configuration file override accounts from the system configuration file. Configuration data from either file can be changed by command line options. A configuration file is a simple text file. Empty lines and comment lines (whose first non-blank character is `#') are ignored. Every other line must contain a command and may contain an argument to that command. The argument may be enclosed in double quotes ("), for example if its first or last character is a blank. If a file name starts with the tilde (~), this tilde will be replaced by $HOME. If a command accepts the argument on, it also accepts an empty argument and treats that as if it was on. Commands are organized in accounts. Each account starts with the account command and defines the settings for one SMTP account. Skip to the EXAMPLES section for a quick start. Commands are as follows: defaults Set defaults. The following configuration commands will set default values for all following account definitions in the current configuration file. account name [:account[,...]] Start a new account definition with the given name. The current default values are filled in. If a colon and a list of previously defined accounts is given after the account name, the new account, with the filled in default values, will inherit all settings from the accounts in the list. host hostname The SMTP server to send the mail to. The argument may be a host name or a network address. Every account definition must contain this command. port number The port that the SMTP server listens on. The default is 25 ("smtp"), unless TLS without STARTTLS is used, in which case it is 465 ("smtps"). timeout (off|seconds) Set or unset a network timeout, in seconds. The argument off means that no timeout will be set, which means that the operating system default will be used. proxy_host [IP|hostname] Use a SOCKS proxy. All network traffic will go through this proxy host, including DNS queries, except for a DNS query that might be necessary to resolve the proxy host name itself (this can be avoided by using an IP address as proxy host name). An empty hostname argument disables proxy usage. The supported SOCKS protocol version is 5. If you want to use this with Tor, see also "Using msmtp with Tor" below. proxy_port [number] Set the port number for the proxy host. An empty number argument resets this to the default port. protocol (smtp|lmtp) Set the protocol to use. Currently only SMTP and LMTP are supported. SMTP is the default. See the port command above for default ports. domain argument Use this command to set the argument of the SMTP EHLO (or LMTP LHLO) command. The default is localhost, which is stupid but usually works. Try to change the default if mails get rejected due to anti-SPAM measures. Possible choices are the domain part of your mail address (provider.example for joe@provider.example) or the fully qualified domain name of your host (if available). auth [(on|off|method)] Enable or disable authentication and optionally choose a method to use. The argument on chooses a method automatically. Usually a user name and a password are used for authentication. The user name is specified in the configuration file with the user command. There are five different methods to specify the password: 1. Add the password to the system key ring. Currently supported key rings are the Gnome key ring and the Mac OS X Keychain. For the Gnome key ring, use the command secret-tool (part of Gnome's libsecret) to store passwords: secret-tool store --label=msmtp host mail.freemail.example service smtp user joe.smith. On Mac OS X, use the Keychain Access GUI application. The account name is same as the user name. The keychain item name is smtp://<hostname> where <hostname> matches the host argument. 2. Store the password in an encrypted files, and use passwordeval to specify a command to decrypt that file, e.g. using GnuPG. See EXAMPLES. 3. Store the password in the configuration file using the password command. (Usually it is not considered a good idea to store passwords in plain text files. If you do it anyway, you must make sure that the file can only be read by yourself.) 4. Store the password in ~/.netrc. This method is probably obsolete. 5. Type the password into the terminal when it is required. It is recommended to use method 1 or 2. Multiple authentication methods exist. Most servers support only some of them. Historically, sophisticated methods were developed to protect passwords from being sent unencrypted to the server, but nowadays everybody needs TLS anyway, so the simple methods suffice since the whole session is protected. A suitable authentication method is chosen automatically, and when TLS is disabled for some reason, only methods that avoid sending clear text passwords are considered. The following user / password methods are supported: plain (a simple plain text method, with base64 encoding, supported by almost all servers), scram-sha-1 (a method that avoids clear- text passwords), cram-md5 (an obsolete method that avoids clear- text passwords), digest-md5 (an overcomplicated obsolete method that avoids clear-text passwords, but is not considered secure anymore), login (a non-standard clear-text method similar to but worse than the plain method), ntlm (an obscure non-standard method that is now considered broken; it sometimes requires a special domain parameter passed via ntlmdomain). There are currently two authentication methods that are not based on user / password information and have to be chosen manually: external (the authentication happens outside of the protocol, typically by sending a TLS client certificate, and the method merely confirms that this authentication succeeded), and gssapi (the Kerberos framework takes care of secure authentication, only a user name is required). It depends on the underlying authentication library and its version whether a particular method is supported or not. Use --version to find out which methods are supported. user login Set the user name for authentication. An empty argument unsets the user name. password secret Set the password for authentication. An empty argument unsets the password. Consider using the passwordeval command or a key ring instead of this command, to avoid storing plain text passwords in the configuration file. passwordeval [eval] Set the password for authentication to the output (stdout) of the command eval. This can be used e.g. to decrypt password files on the fly or to query key rings, and thus to avoid storing plain text passwords. ntlmdomain [domain] Set a domain for the ntlm authentication method. This is obsolete. tls [(on|off)] Enable or disable TLS (also known as SSL) for secured connections. You also need tls_trust_file or tls_fingerprint, and for some servers you may need to disable tls_starttls. Transport Layer Security (TLS) "... provides communications privacy over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery" (quote from RFC2246). A server can use TLS in one of two modes: via a STARTTLS command (the session starts with the normal protocol initialization, and TLS is then started using the protocol's STARTTLS command), or immediately (TLS is initialized before the normal protocol initialization; this requires a separate port). The first mode is the default, but you can switch to the second mode by disabling tls_starttls. When TLS is started, the server sends a certificate to identify itself. To verify the server identity, a client program is expected to check that the certificate is formally correct and that it was issued by a Certificate Authority (CA) that the user trusts. (There can also be certificate chains with intermediate CAs.) The list of trusted CAs is specified using the tls_trust_file command. Usually there is some system-wide default file available, e.g. /usr/local/share/certs/ca-root-nss.crt on Debian-based systems, but you can also choose to select the trusted CAs yourself. One practical problem with this approach is that the client program should also check if the server certificate has been revoked for some reason, using a Certificate Revocation List (CRL). A CRL file can be specified using the tls_crl_file command, but getting the relevant CRL files and keeping them up to date is not straightforward. You are basically on your own. A much more serious and fundamental problem is is that you need to trust CAs. Like any other organization, a CA can be incompetent, malicious, subverted by bad people, or forced by government agencies to compromise end users without telling them. All of these things happened and continue to happen worldwide. The idea to have central organizations that have to be trusted for your communication to be secure is fundamentally broken. Instead of putting trust in a CA, you can choose to trust only a single certificate for the server you want to connect to. For that purpose, specify the certificate fingerprint with tls_fingerprint. This makes sure that no man-in-the-middle can fake the identity of the server by presenting you a fraudulent certificate issued by some CA that happens to be in your trust list. However, you have to update the fingerprint whenever the server certificate changes, and you have to make sure that the change is legitimate each time, e.g. when the old certificate expired. This is inconvenient, but it's the price to pay. Information about a server certificate can be obtained with --serverinfo --tls --tls-certcheck=off. This includes the issuer CA of the certificate (so you can trust that CA via tls_trust_file), and the fingerprint of the certificate (so you can trust that particular certificate via tls_fingerprint). TLS also allows the server to verify the identity of the client. For this purpose, the client has to present a certificate issued by a CA that the server trusts. To present that certificate, the client also needs the matching key file. You can set the certificate and key files using tls_cert_file and tls_key_file. This mechanism can also be used to authenticate users, so that traditional user / password authentication is not necessary anymore. See the external mechanism in auth. tls_starttls [(on|off)] Choose the TLS variant: start TLS from within the session (on, default), or tunnel the session through TLS (off). tls_trust_file file Activate server certificate verification using a list of truted Certification Authorities (CAs). The file must be in PEM format. Some systems provide a system-wide default file, e.g. /usr/local/share/certs/ca-root-nss.crt on Debian-based systems with the ca-certificates package. An empty argument disables this. You should also use tls_crl_file. tls_crl_file [file] Set a certificate revocation list (CRL) file for TLS, to check for revoked certificates. An empty argument disables this. tls_fingerprint [fingerprint] Set the fingerprint of a single certificate to accept for TLS. This certificate will be trusted regardless of its contents. The fingerprint can be either an SHA1 (recommended) or an MD5 fingerprint in the format 01:23:45:67:.... Use --serverinfo --tls --tls-certcheck=off to get the server certificate fingerprints. tls_key_file file Send a client certificate to the server (use this together with tls_cert_file}). The file must contain the private key of a certificate in PEM format. An empty argument disables this feature. tls_cert_file file Send a client certificate to the server (use this together with tls_key_file). The file must contain a certificate in PEM format. An empty argument disables this feature. tls_certcheck [(on|off)] Enable or disable checks of the server certificate. WARNING: When the checks are disabled, TLS sessions will be vulnerable to man-in-the-middle attacks! tls_min_dh_prime_bits [bits] Set or unset the minimum number of Diffie-Hellman (DH) prime bits that mpop will accept for TLS sessions. The default is set by the TLS library and can be selected by using an empty argument to this command. Only lower the default (for example to 512 bits) if there is no other way to make TLS work with the remote server. tls_priorities [priorities] Set the priorities for TLS sessions. The default is set by the TLS library and can be selected by using an empty argument to this command. See the GnuTLS documentation of the gnutls_priority_init function for a description of the priorities string. from envelope_from Set the envelope-from address. This address will only be used when auto_from is off. auto_from [(on|off)] Enable or disable automatic envelope-from addresses. The default is off. When enabled, an envelope-from address of the form user@domain will be generated. The local part will be set to USER or, if that fails, to LOGNAME or, if that fails, to the login name of the current user. The domain part can be set with the maildomain command. If the maildomain is empty, the envelope-from address will only consist of the user name and not have a domain part. When auto_from is disabled, the envelope- from address must be set explicitly. maildomain [domain] Set a domain part for the generation of an envelope-from address. This is only used when auto_from is on. The domain may be empty. dsn_notify (off|condition) This command sets the condition(s) under which the mail system should send DSN (Delivery Status Notification) messages. The argument off disables explicit DSN requests, which means the mail system decides when to send DSN messages. This is the default. The condition must be never, to never request notification, or a comma separated list (no spaces!) of one or more of the following: failure, to request notification on transmission failure, delay, to be notified of message delays, success, to be notified of successful transmission. The SMTP server must support the DSN extension. dsn_return (off|amount) This command controls how much of a mail should be returned in DSN (Delivery Status Notification) messages. The argument off disables explicit DSN requests, which means the mail system decides how much of a mail it returns in DSN messages. This is the default. The amount must be headers, to just return the message headers, or full, to return the full mail. The SMTP server must support the DSN extension. add_missing_from_header [(on|off)] This command controls whether to add a From header if the mail does not have one. The default is to add it. add_missing_date_header [(on|off)] This command controls whether to add a Date header if the mail does not have one. The default is to add it. remove_bcc_headers [(on|off)] This command controls whether to remove Bcc headers. The default is to remove them. logfile [file] An empty argument disables logging (this is the default). When logging is enabled by choosing a log file, msmtp will append one line to the log file for each mail it tries to send via the account that this log file was chosen for. The line will include the following information: date and time, host name of the SMTP server, whether TLS was used, whether authentication was used, authentication user name (only if authentication is used), envelope-from address, recipient addresses, size of the mail as transferred to the server (only if the delivery succeeded), SMTP status code and SMTP error message (only in case of failure and only if available), error message (only in case of failure and only if available), exit code (from sysexits.h; EX_OK indicates success). If the filename is a dash (-), msmtp prints the log line to the standard output. syslog [(on|off|facility)] Enable or disable syslog logging. The facility can be one of LOG_USER, LOG_MAIL, LOG_LOCAL0, ..., LOG_LOCAL7. The default is LOG_USER. Each time msmtp tries to send a mail via the account that contains this syslog command, it will log one entry to the syslog service with the chosen facility. The line will include the following information: host name of the SMTP server, whether TLS was used, whether authentication was used, envelope-from address, recipient addresses, size of the mail as transferred to the server (only if the delivery succeeded), SMTP status code and SMTP error message (only in case of failure and only if available), error message (only in case of failure and only if available), exit code (from sysexits.h; EX_OK indicates success). aliases [file] Replace local recipients with addresses in the aliases file. The aliases file is a plain text file containing mappings between a local address and a list of domain addresses. A local address is defined as one without an `@' character and a domain address is one with an `@' character. The mappings are of the form: local: someone@example.com, person@domain.example Multiple domain addresses are separated with commas. Comments start with `#' and continue to the end of the line. The local address default has special significance and is matched if the local address is not found in the aliases file. If no default alias is found, then the local address is left as is. An empty argument to the aliases command disables the replacement of local addresses. This is the default.

This method is probably not # relevant anymore. # Password method 5: Do not specify a password. Msmtp will then prompt you for # it. This means you need to be able to type into a terminal when msmtp runs. # A second mail address at the same freemail service account freemail2 : freemail from joey@freemail.example # The SMTP server of your ISP account isp host mail.isp.example from smithjoe@isp.example auth on user 12345 # Set a default account account default : freemail Using msmtp with Mutt Create a configuration file for msmtp and add the following lines to your Mutt configuration file: set sendmail="/path/to/msmtp" set use_from=yes set realname="Your Name" set from=you@example.com set envelope_from=yes The envelope_from=yes option lets Mutt use the -f option of msmtp. Therefore msmtp chooses the first account that matches the from address you@example.com. Alternatively, you can use the -a option: set sendmail="/path/to/msmtp -a my-account" Or set everything from the command line (but note that you cannot set a password this way): set sendmail="/path/to/msmtp --host=mailhub -f me@example.com --tls --tls-trust-file=trust.crt" If you have multiple mail accounts in your msmtp configuration file and let Mutt use the -f option to choose the right one, you can easily switch accounts in Mutt with the following Mutt configuration lines: macro generic "<esc>1" ":set from=you@example.com" macro generic "<esc>2" ":set from=you@your-employer.example" macro generic "<esc>3" ":set from=you@some-other-provider.example" Using msmtp with mail Define a default account, and put the following in your ~/.mailrc: set sendmail="/path/to/msmtp" Using msmtp with Tor Use the following settings: proxy_host 127.0.0.1 proxy_port 9050 tls on Use an IP address as proxy host name, so that msmtp does not leak a DNS query when resolving it. TLS is required to prevent exit hosts from reading your SMTP session. You also need tls_trust_file or tls_fingerprint to check the server identity. Do not set domain to something that you do not want to reveal (do not set it at all if possible).

FILES

SYSCONFDIR/msmtprc System configuration file. Use --version to find out what SYSCONFDIR is on your platform. ~/.msmtprc User configuration file. ~/.netrc and SYSCONFDIR/netrc The netrc file contains login information. Before prompting for a password, msmtp will search it in ~/.netrc and SYSCONFDIR/netrc.

ENVIRONMENT

USER, LOGNAME These variables override the user's login name when constructing an envelope-from address. LOGNAME is only used if USER is unset. TMPDIR Directory to create temporary files in. If this is unset, a system specific default directory is used. A temporary file is only created when the -t/--read-recipients or --read-envelope-from option is used. The file is then used to buffer the headers of the mail (but not the body, so the file won't get very large). EMAIL, SMTPSERVER These environment variables are used only if neither --host nor --account is used and there is no default account defined in the configuration files. In this case, the host name is taken from SMTPSERVER, and the envelope from address is taken from EMAIL, unless overridden by --from or --read-envelope-from. Currently SMTPSERVER must contain a plain host name (no URL), and EMAIL must contain a plain address (no names or additional information).
