Hi.  I'm new to this list (subscription still pending) and new to
milter-greylist.  I did look around postings over the last 2 months,
and apologize if I'm raising something that has already been resolved,
but I didn't see anything exactly like this (but did see some close.)


The greylisting delay can hurt legitimate users, if they are part of
collaborative group. Milter-greylist has various features to permit
configured whitelisting, but it doesn't seem to have the one I'm think
would help my system:

Most of the people sending mail to that system are participating in
some (mailman-based) mailing lists.  They send from different
machines; even the same person does.  Worse, the membership of the
mailing lists varies over time.

This means that members of pre-approved communities -- by virtue of
their mailing list subscription -- are regularly having the postings
delayed.  In an active group discussion, having random postings show
up 30 minutes late can make a difference.

I am thinking that it would be good to have milter-greylist able to
query the membership of a mailing list and automatically accept mail
with an rfc2822.From header field address that is subscribed to the
destination mailing list.  This needs to be a dynamic query, in order
to guarantee that the subscription membership that is used is accurate.

Comments?
