Hello.
I have SpamassAssin running but I want to change its behaviour.
Although I'm subscribed to this list from time ago, but this is my first
post (as far as I can remember). If this message is not adequate here,
please, redirect me to the correct place.
I have SpamAssassin in my Debian box (with sendmail). I have config A)
where spamassassin is run in the delivery stage of the sendmail (see the
apendixes below) and I desire behaviour B) where it is run at the
incoming stage so the spam is rejected and the sender cannot success at
sending it.
QUESTION-1: Is this possible?
Yes. There's a group of utilities for sendmail called "milters", which
are "mail filters" that run during the STMP session.
There are 2 I can directly think of that would help you.
mimedefang is the first one. It's a great, and very flexible, utility
... but it requires some expertise with the perl programming language.
amavis is the other one. I know very little about amavis, but I know it
has a milter capability, and can be used with spam assassin.
I think there's also a more direct "spam assassin milter", but I don't
have any details about it.
QUESTION-2: May I break this goal into small parts and achieve each
separately?
I'm not sure what you mean. Do you mean a gradual phasing in of the new
method? You could, for example:
1) install mimedefang, and keep using spam assassin the way you currently do
2) move spam assassin to mimedefang instead of during delivery
3) change mimedefang's mimedefang-filter so that it rejects during SMTP
instead of just adding headers
QUESTION-3: Where do I have to start?
Google search for mimedefang and amavis and "spamassassin milter".
Investigate each. Find mailing lists for each. As for help on those
mailing lists.
