This would be an entirely different application, not SA, wouldn't it?
It can be developed using the same "spam score" logic, based subset of
all tests requiring only the subset of "final data" available during
"classic run".
So in other words something like SMTP-time DNSBL tests that score points
towards rejection rather than being pass/fail? That sounds like a good
idea.
I do think that promoting tools that encourage postmaster to care very
much about mail server (IP address) reputation can make real difference
e.g. caring to be above reputation "none" in DNSWL to avoid grey-listing.
Agreed. But, performing major redesign of SA to achieve this pre-RCPT is
going to be a tough sell.
Well, this probably could be done in SA using a multi-level protocol
capable of returning values at different stages. However, this seems
perfectly suited for a lightweight tool, rather than a hog that is
designed to scan and process entire messages. :)
During initial tests/deployment *much* simpler implementation can be
used with recommended action based on spam score:
It would require redesign of 50_scores.cf structure.
e.g. instead of
score RCVD_IN_DNSWL_HI 0 -8 0 -8
something like that
# N - Network, B - Bayes, nX - no X, R - "RCPT TO:"
score RCVD_IN_DNSWL_HI nNnB=0 NnB=-8 nNB=0 NB=-8 R=-8
or shorter
score RCVD_IN_DNSWL_HI N=-8 R=-8
Why would SA be served by _major_ modifications like this, rather than
writing a new milter that focuses on determining the reputation of an IP?
Are you really willing to break _all_ existing SA installations for this?
Please don't try to make SA a "do everything" tool, you'll likely weaken
what it does an outstanding job of today.
