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:
- use spamass-milter
sender -> sendmail -> exchange server where sendmail talk to spamass-milter -> spamc -> spamd (spamassassin)
- 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?
