Needing a guide/tutorial please

[Steve Lake]

         Looking for a guide online somewhere that will walk me through 
setting up a mail server with the following items on it.

SpamAssassin
Postfix (pop3 and smtp setup)
MySQL (for database driven mail user administration)
MyPHPAdmin (to visually admin the database)
Squirrelmail (for webmail)
Apache (for squirrelmail)
Dovecot Imap (for squirrelmail)
Postfix Admin <- this is the reason for the need to have a mysql driven 
mail user database.  It's apparently required for this to work.  Plus 
database driven user management tends to be easier.  Of course, if you know 
of a better way to graphically admin mail users without using a database, 
I'm all ears.  :)
And lastly, some kind of web based server admin page that's similar to 
webmin, but more secure.

         I want to setup a mail server with all these elements, have 
postfix, squirrelmail and dovecot be database driven and somehow create a 
mailbox tree for the webmail users for saved, spam, sent and trashcan 
folders.  Also, lastly, which format for mail is better?  Maildir or 
Mbox?  I'm partial to Mbox, but I've heard some others say Maildir is 
better.  The server is only going to host about 30-40 users for a realty 
company, so security is priority, plus it needs to have ease of 
administration because the guy who's going to admin this in the end (I'm 
just building it, he's maintaining it) isn't unix savy.  I've already done 
a lot of google diving, but with little luck.  Hence why I'm asking 
here.  If someone knows of a good guide or series of guides that'll help me 
through all this, it'd be greatly appreciated.  I'm used to doing this the 
hard way with sendmail and the regular freebsd users through the 
console.  So I'm really new to postfix, but I'm using it because it's 
supposedly more secure.  I'd have the guy who's admining it do the same, 
but he's too green in the console to risk it.  ;)

         Many thanks in advance for any help you can provide.  :)
