[RFCI-Discuss] Postmaster/abuse listings

[Stewart James]

It is doable.

FEATURE(`delay_checks',`friend')dnl

>From cf.README

delay_checks    The rulesets check_mail and check_relay will not be called
        when a client connects or issues a MAIL command, respectively.
        Instead, those rulesets will be called by the check_rcpt
        ruleset; they will be skipped under certain circumstances.
        See "Delay all checks" in the anti-spam configuration control
        section.  Note: this feature is incompatible to the versions
        in 8.10 and 8.11.

which then means you should be able to whitelist domains/IP's that have
been blacklisted on a list somewhere, or make it so certain email address'
do not get checked on the lists.

I don;t have any email servers that are blacklisted myself to test this
from, but a couple I have had to whitelist seem to have worked. Also had
some email to postmaster from blacklisted IP's aswell.

Cheers,

Stewart
