For anyone wanting to setup a mail server this is the best guide going. I read Part 1 and had to find my own way. Incidentally, if you are trying to read email or send email with code, having your own email server, working with a desktop client is a very useful starting point. You can downgrade the spam filtering, the SPF record checking, the SSL/TLS sign on until you have something that can read IMAP or POP. This is where the real fun begins as emails come in various multi-part formats, there are lots of character sets to translate to UTF-8 and there is base64 to deal with. If you can reliably read the header of an email and extract something simple like the date then you are doing very well.
