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/lib/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.

· 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

· Ex Output: ( POD wrapping will mess this up, view source )
