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.
