Yes! I run three mail servers. I have all three running on separate Linodes. I could probably combine them into one server, but I use them for different purposes. Each server consists of: 0. Debian 1. postfix 2. courier 3. sasl 4. postgresql authentication 5. enable blacklist blocking 6. TBD - setting up fail2ban. I could post a config for each component, but that may get lengthy. The hardest part of figuring out the setup for me was remembering to configure the groups correctly for sasl socket access. It's definitely worth running my own server. Linode has a $10/month server which would easily handle all email for you and few friends/family. The setup is very easy. Just remember to public-key your ssh access and then lock any passwords. I get nearly no spam mail, and it's lots of fun to watch the blocking log entries go by... EDIT: my list didn't come out as a list -- unfamiliar with the tagging possibilities on this site - if any...
