Package: logcheck-database
Version: 1.2.54
Severity: wishlist
Enabling reject_unknown_sender_domain allows one to filter out some of
the crap that spammers send, but it often generates one or two warnings.
Here are some ignore rules to weed those out:
^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ postfix/smtpd\[[[:digit:]]+\]:
warning: numeric hostname: [0-9.]{7,15}$
^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ postfix/smtpd\[[[:digit:]]+\]:
warning: valid_hostname: empty hostname$
^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ postfix/smtpd\[[[:digit:]]+\]:
warning: malformed domain name in resource data of MX record for
[._[:alnum:]-]+:.*$
The first warning is issued when the MAIL FROM domain reverse-resolves
to an all-numeric hostname (like 84.16.227.85 at the moment), while the
other two are issued together when the MAIL FROM domain has an MX record
with garbage in it (usually ".").
