postgreyreport - Fatal report for Postfix Greylisting Policy Server

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

     --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.

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

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

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 )
