POSTGREYREPORT(1) User Contributed Perl Documentation POSTGREYREPORT(1) 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. 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 ) :============================================================================================ unknown 184.108.40.206 email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org :============================================================================================ lsanca1-ar5-127-189.biz.dsl.gtei.net 220.127.116.11 A email@example.com firstname.lastname@example.org email@example.com firstname.lastname@example.org :============================================================================================ smtpout.mac.com 18.104.22.168 email@example.com firstname.lastname@example.org smtpout.mac.com 22.214.171.124 MX email@example.com firstname.lastname@example.org :============================================================================================ HISTORY 1.14.3 20100321 Some additions, Leonard den Ottolander <leonard.den.ottolander.nl> New option: --tab Use tabs as separator in single line mode New option: --show_time Show entry time in maillog in single line mode 1.14.2 20040715 BUGFIX: (automatic) lookup-by-subnet support was broken, fixed.
