You can configure postfix to listen example 127.0.0.1:25 where it won't do anymore any content checking, where you feed message from dspam.
Then you have example 192.168.0.1:25 what will do content filtering and sends mail to dspam for scanning. so: postfix -> dspam -> postfix -> cyrus > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Eric Brunson > Sent: Thursday, February 21, 2008 1:43 AM > To: [email protected] > Subject: [dspam-users] Setup recommendations > > > I'm currently using spamassassin to tag my spam, but I've > been talking about switching to dspam for a long time and > finally have a server to set it up on for testing. > > My existing set up is like this: > > postfix --(via content-filter)-> spamd --(via sendmail > wrapper)-> postfix --(via lmtp)-> cyrus-imapd > > What I'd like to move to would be: > > postfix --(via lmtp)-> dspam --(via lmtp)-> cyrus-imapd > > and later add clamav through dspam's built in support. > > First of all, is that a reasonable architecture?
