Hello,
I am looking at a system where SpamAssassin is called out from the
delivery agent. I know there will be a difference here in terms of
the
envelope information but I'm not familiar enough to know the pitfalls
of this versus calling SA from the postfix content_filter.
You can call spam assassin from an LDA like procmail or sieve, but
that is not a topic for this list.
Calling SA during the transaction is much better though, since it
allows you to drop very spammy messages as undeliverable.
Appreciate the reply, but I wasn't asking how to set it up. I thought my
question made it clear I was asking about the pros/cons of the placement
of SA in the mail flow. Please see my message just sent a minute ago for
another try.
By the way it is my impression that, at least for sites with volume
above that of a home or very small business, calling out to filters like
SA or clam during the SMTP transaction can really kill performance and
that it's best to simply send messages scored very highly to the bit
bucket.
