Re: [TUHS] Who is running their own mail server and what do you run?

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 - Spamhaus - Drop v4 - eDrop v4 - Drop v6 - DShield I also do the following, but they don't strictly impact inbound email filtering. - I publish DNS records for - SPF w/ -all - DKIM - 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'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.
