NAME
postgreyreport - Fatal report for Postfix Greylisting Policy Server
SYNOPSIS
postgreyreport [options...]
-h, --help display this help and exit
--version display version and exit
--user=USER run as USER (default: postgrey)
--dbdir=PATH find db files in PATH (default: /var/db/postgrey)
--delay=N report triplets that did not try again after N seconds (default: 300)
--greylist-text=TXT text to match on for greylist maillog lines
--skip_pool Skip report for 'subscriber pools' ( last 2 octets of IP found in PTR name )
--skip_dnsbl=RBL RBL server to query and skip reporting for any listed hosts (SLOW!!)
--skip_clients=FILE PTR or IP or REGEXP of clients to skip in report
--match_clients=FILE *ONLY* report if fatal *AND* PTR/IP of client matches
--show_tries display the number of attempts failed triplets made in first column
--show_time show entry time in maillog (single line only)
--tab use tabs as separators for easy cut(1)ting
--nosingle_line display sender/recipients grouped by ptr - ip
--separate_by_subnet=TXT display TXT for every new /24 (ex: "=================\n" )
--separate_by_ip=TXT display TXT for every new IP (ex: "\n")
--check_sender=LIST one or more of: mx,mx/24,a,a/24
does DNS/A lookups for sender @domain and compares sending IP
if match displays "MX" "A" or "MX/24" or "A/24" depending on LIST
Note that --(skip|match)_clients can be specified multiple times and there are no default files.
Same rules apply as postgrey's --whitelist-clients, see postgrey doc for more info.
--skip_dnsbl can also be specified multiple times to query multiple DNSBL servers.
DESCRIPTION
postgreyreport opens postgrey.db as read-only; reads a maillog via
STDIN, extracts the triplets for any Greylisted lines and looks them
up in postgrey.db. if the difference in first and last time seen is
less than --delay=N then the triplet is considered fatal and displayed
to STDOUT
The report sorts by client IP address
Note:
unless you are using --lookup_by_subnet or excluding all known MTA
pools you will likely have false fatal reports for "BigISPs". A message
that was tried from every IP in SMTP pool before making it through will
show up in the report for all of the attempted source IPs
USAGE
It is best to run postgreyreport against a maillog that is at least
several hours old (yesterdays?) ( you be the judge on how old is
acceptable ). if you run the report against a live maillog you are not
giving legit MTA's enough time to try again and you will have lots of
inaccurate information.
o Ex usage:
zcat /var/log/maillog.0.gz | ./postgreyreport [options] > postgreyreport.log
or
zcat /var/log/maillog.0.gz | \
./postgreyreport --nosingle_line --check_sender=mx,a \
--separate_by_subnet=":==================\n"
# 94 "=" total, some were omitted for clarity
o Ex Output: ( POD wrapping will mess this up, view source )
