That most of my mail comes from 100% assured not spam sources: mailing lists that are already filtered or rss2email (the second probably can be skipped easily because it comes locally).

What kind of VPS are you using ? I'm in a similar boat to you, running my own domain(s) and email, and have built the mail system on a set of 3 VPS', two 6G ram that cost $7/mo and one 1G ram that's $3.50/mo. The two larger ones run exim4, spamassassin, clamav, nginx, roundcube, dovecot, munin (stats), solr (search), zpush, tinyrss, percona (mysql).
It all works swimmingly well. The main setup will run in a 2G ram VPS, albeit with some swapping. If you're on an SSD-backed VPS, it works OK - that was my old setup with Digital Ocean.
ClamAV is the memory hog, spamassassin really isn't bad , so you might give it a shot ...

All the mysql stuff is a 3-node replication cluster, the two main systems and a 3rd (small one) just running percona. Dovecot is also replicating between the two main systems. This way ALL the data is replicated between them, and I can hit either main system for all functionality. Replication is over tinc encrypted sessions.
