One step toward regaining autonomy using FOSS: Best practices for email hosting

whh3 writes: After reading the recent Doc Searls article in Linux Journal, I realized that I need to get back to my roots. The first step will be to build/setup/run my own email server for my vanity domain.

The problem is, I haven't run my own email server since the 90s. It was easy back then — there was much less SPAM and self-hosted email servers didn't have to jump through hoops to make sure that they weren't blacklisted as senders.

So, I am reaching out to this great community to find out if there are any good tutorials on modern-day best-practices for self hosting an email server. Any tips/tricks/pointers would be great appreciated!
