I want to integrate my sendmail MTA (relaying only, no local mailboxes) with spamassassin. Sendmail box sits between internal MS Exchange server and internet. So, I see two options for doing this (or there are more?), depicted bellow schematically:

  1. use spamass-milter
  sender -> sendmail -> exchange server

      where sendmail talk to spamass-milter -> spamc -> spamd (spamassassin)
  1. use spampd (spamassassin proxy daemon, do not confuse it with spamd)
 sender -> sendmail -> spampd -> exchange server

        where spampd talks to spamassassin

I want to know your opinion: which option is better, what are the pros and cons of each one?

is sendmail a requirement or are other options such as postfix being considered? – pablo Mar 1 '11 at 23:17
I have already implemented sendmail and want to stay with it. – user71061 Mar 1 '11 at 23:37
ok if you change your mind consider this: assp.sourceforge.net... actually that works with sendmail too – pablo Mar 1 '11 at 23:39

We use policyd-weight for filtering. Its works fine. But i think solution one is enough.

But isn't it something completely different from spamassassin? – user71061 Mar 1 '11 at 23:36
its a spamfilter you can read the specification on the site ;). we use policyd-weight -> spamass (if you need it) for Postfix. Aber them you can make a relay to your exchange server. – Stony Mar 1 '11 at 23:43
