[Nottingham] logwatch and sendmail 8.12 dnsbl

[James Beckett]

It's just occurred to me that although logwatch tags a raft of
sendmail rejects, DNSBL rejects don't show up. This bugs me, as I'd
like metrics for the effectiveness of my various spam protection
systems.

In sendmail 8.12, lines in /var/log/maillog take the form:

Feb  3 12:46:17 xyzzy sendmail[26622]: ruleset=check_relay,
  arg1=lsanca1-ar20-4-65-076-224.lsanca1.dsl-verizon.net,
  arg2=4.65.76.224,
  relay=lsanca1-ar20-4-65-076-224.lsanca1.dsl-verizon.net [4.65.76.224],
  reject=550 5.7.1 Rejected: 4.65.76.224 listed at relays.visi.com

which doesn't seem to match any of the patterns in logwatch's sendmail
script, in either my version (4.3) or the current version on the
logwatch website. This is the standard format output by the m4 macro
invocation

   FEATURE(`dnsbl',`relays.visi.com')dnl

There's some mention in the logwatch mailing list from Jun 2002 about
DNSBL handling but no followup. Does anyone here have this working,
before I bug the logwatch author?
