On my old server I am running Postfix, mail/postgrey and Postscreen (as well as Spamassassin and ClamAV but that is not relevant to this post). This combination has been fantastic since I implemented it. The only annoying issue with Postgrey has been (obviously) the delays in email delivery at times.
I am now considering running the same setup as above but replacing Postgrey with mail/milter-greylist. I see that milter-greylist does whitelisting by default and can blacklist or greylist depending on the rules set in the config file.
The questions I have are:
1) If I continue using Postscreen, is there anypoint in using milter-greylist with DNS RBLs?
2) Is it better to drop Postscreen and just use milter-greylist? ie: Use milter-greylist to do ALL DNS RBL checking, blacklisting/greylisting/whitelisting?
Ideally I would like to keep Postscreen as it has been super. I would also like to use greylisting but would like more control over it and like milter-greylists default behaviour of whitelisting (there are obviously rules before the whitelisting rule to greylist or blacklist).
I'd be interested in hearing the forums thought on this, especially on milter-greylist.
Thank you.
