I'm running Sendmail (the 800 lb gorilla that I know) on multiple Linode
VPSs. (I can highly recommend Linode.)
My email stack is fairly straightforward:
- Sendmail + milters
- ClamAV - can reject email at SMTP time
- OpenARC - adds headers for SpamAssassin
- OpenDKIM - adds headers for SpamAssassin
- OpenDMARC - adds headers for SpamAssassin
- SpamAssassin - can reject email at SMTP time
- SPFmilter - can reject email at SMTP time
- JunkEmailFilter Project Tarbaby as a high order / low priority MX
- Reverse Path IP filtering
- Team Cymru Bogons
- Full IPv4
- Full IPv6
- Drop v4
- eDrop v4
- Drop v6
I also do the following, but they don't strictly impact inbound email
- I publish DNS records for
- SPF w/ -all
- DMARC w/ strict rejections on all messages
- DNSSEC signed zones & published DS records.
- I recently added Sender Rewrite Scheme to my mail server.
- I now host email for a friend that he wants forwarded
(unmodified) to Gmail.

I may end up regretting saying this, but I don't think my spam problem
is nearly as bad as other people seem to have it.

I've found my solution to be mostly maintenance free.
I do dabble, by choice, and recently wrote a proto MTA in Perl to
experiment with gray listing.
I also have > 2k lines of procmail recipes, but that's almost all for
filtering different addresses into the multiple hundreds of folders I
have in my personal email account.
Ask if you want any more details.
