Sorry, here's the guide I just started.

Why from a different e-mail address?
That's something the list admins need to look into, it seems every time I post to this list within seconds I end up on Spamhaus blacklist.
Doesn't happen elsewhere, just this list, and it's annoying as hell.

Hello All,
I need to set up a new mail server to replace an aging CentOS 6.3 mail
server. I was wondering what were some of the best guides on the web for Postfix (Maildir), Spamassassin, ClamAV, Dovecot?
Probably not what you are looking for and it still has bugs, but I just (within last five days) started this project for securing outbound SMTP from a Postfix server, taking DANE, MTA-STS, and STARTTLS Everywhere policies into consideration.
One thing I will note, don't use the Postfix that ships with CentOS 7.x. It was fine when 7.0 shipped, but you really want to be using 3.2 or newer now.
