I'm trying to clarify the various ways in which I could set up Postfix + Dovecot + SpamAssassin under CentOS-7, and I'd welcome any comments on the following remarks.
As far as I can see there are 3 standard ways of setting this up:
- Use amavisd
- Use dovecot + pigeonhole/sieve
- Use spamass-milter
At present I'm following (2), but am thinking of going over to (1), since this seems simpler. (Amavisd wasn't available when I set up CentOS-7, so I didn't consider it then.)
It seems to me that (2) is using dovecot in a slightly odd way, since as far as I can see dovecot normally takes email from ~/Maildir/cur/ and then moves marked spam.
I'm not quite sure if (3) is a genuine alternative, or if it is why it is not the standard?
