I've also heard good things about "The Book of Postfix". Even though
it is quite old now, most of the parts/concepts/terminology still
apply today. Part of it is also available on Google Books.
Despite being quote oldies you say, this is a great resource for
understanding not just postfix, but how email in general works. I
think it would be a handy primer for anyone trying to be a mail admin,
as the concepts have not changed even if some of the commands and
configurations have. Modern Postfix has more and better tools that are
not mentioned in the book, especially for dealing with unwanted mail,
but as a baseline, the book is still worthwhile.
ersonally, I would take things step by step and not try to install and
configure everything all at once.
If you have the time, hang out reading the postfix and dovecot mailing
lists, and searching the archives. Look for configuration questions
that people have discussed. Do not really on a google search for
something like :how to setup postfix and dovecot" because most of
these results will be garbage, outdated, m or contain flat-out errors.
Pay close attention to the syntax of sample configs people post, and
especially to the comments and corrections of those samples.
Also, the man pages for Postfix are very good.
The most important thing to get straight is that what you think might
be the best plan for configuring your mail may in fact be a terrible
idea, and you really want to do the research first.
Understanding exactly where the separation is between postfix and
dovecot is crucial, and even people who've been doing this a lot can
get caught out sometimes.
The Dovecot web docs are decent enough and cover the information, but
I find them to be sometimes sparse on details and examples, and they
are not really designed for someone starting out IMO. More for
refreshing something you forgot or misremembered. Searching the list
for doveconf outputs might be more fruitful, as long as you follow the
threads for comments and corrections.
Whatever you do, do not setup unauthticated submission, or submission
that used deprecated security settings no matter how much you thin
this is a good idea. It's not. If you have to support people using
ancient software, force them to use a email client like Horde or
Roundcube so you maintain your mail security. IMO, YMMV. TANSTAAFL.
IANAL. ETC.
Oh, and consider if you really need or want to support POP3 (I
recommend not unless you have a users who want to use Gmail to suck in
their mail). The more mail you are dealing with, the worse POP3 is on
your system and your users.
