Hi all,
I’m trying to integrate dspam into my mail flow and have got some conflict
configuration suggestions.
Regarding on incoming mail what are the advantages of using dspam as a content
filter (and then reinjecting into postfix)[1] vs postfix delivering it to dspam
who then delivers it to dovecot[2]?
Using dspam as a content_filter is no better than using it as your LDA,
since it still passes through a second MTA, and cannot be rejected.
Using a pre-queue spam filter (which can reject or drop mail) has
numerous disadvantages, the biggest ones of which are inability to act
on resolved aliases, processing time, and most importantly: the risk of
false positives, since these will be final and not subject to user review.
I use dspam in line with dovecot, all via LMTP:
postfix -> LMTP -> dspam -> LMTP -> dovecot
It works perfectly; dspam marks the spam and dovecot + pigeonhole sieves
it into folders.
None of this is really list material, I am merely stating my solution
and preference.
If you have problems setting up the postfix side of this, ask directed
questions.
