NAME
     popper - POP3 server

SYNOPSIS
     popper [-k] [-a plaintext|otp|sasl] [-t file] [-T seconds] [-d] [-i]
            [-p port] [--address-log=file]

DESCRIPTION
     popper serves mail via the Post Office Protocol.  Supported options
     include:

     -a plaintext|otp|sasl
             Tells popper which authentication mode is acceptable, sasl
             enables SASL (RFC2222),  and otp enables OTP (RFC1938)
             authentication. Both disable plaintext passwords.

     --address-log=file
             Logs the addresses (along with a timestamp) of all clients to the
             specified file. This can be used to implement POP-before-SMTP
             authentication.

     -d      Enables more verbose log messages.

     -i      When not started by inetd, this flag tells popper that it has to
             create a socket by itself.

     -k      Tells popper to use Kerberos for authentication. This is the
             traditional way of doing Kerberos authentication, and is normally
             done on a separate port (as it doesn't follow RFC1939), and
             should be used instead of using SASL.

     -p port
             Port to listen to, in combination with -i.

     -t file
             Trace all commands to file.

     -T seconds
             Set timeout to something other than the default of 120 seconds.

AUTHORS
     The server was initially developed at the University of California,
     Berkeley.

     Many changes have been made as part of the KTH Kerberos distributions.
