CentOS - May 2005 - Install Guide for PostFix (with DoveCot, SquirrelMail, MailScanner, ClamAV) on CentOS-4

Ok, I have been working (for quite a while) on an install guide for
PostFix (with DoveCot, SquirrelMail, MailScanner, ClamAV) on CentOS-4.

A full install is part 1 (Postfix / Dovecot / Cyrus-Sasl), Part 3
(SquirrelMail) and Part 4 (MailScanner, Spam Assassin, ClamAV).


I am still working on Part 2 (Postfix / Cyrus-Imap / Cyrus-Sasl).  It
will go with Part 3 and Part 4 (same as above) to get a full install
that includes Cyrus-Imapd instead of dovecot ... should be done with
this one in the next couple days.

So to reiterate, Part 1,3,4 is a full postfix/dovecot install ... it is
done and ready to go.  Parts 2,3,4 is a full postfix/cyrus-imapd
install ... this one is not quite done yet.

Part 1 is here:

Hello,

I'd like to thank you very much for this guide (I followed it to install 
my own system two or three weeks back and am still fooling with it).

However there's a few pointers :)

a) PostFix can be run with only one instance in 'hold all' mode
    (found references to this on some mailscanner installation site
    by accident).
    although I haven't yet figured out how to do this without
    having to remove postfix-autostart from the
    /etc/init.d/MailScanner script
    (although that's trivial and makes the startup script very normal)

b) enabling smtps is useful

c) check_relay_domains is outdated
    (should be reject_unauth_destination)

    and indeed more stuff could be placed
    in smtpd_recipient_restrictions

d) I've added a whitelist, spf log-only (I'm pretty much
    convinced spf is stupid, but loggin it is informative)
    and greylisting to mine, these could also probably be mentioned
    in the quide?

e) Some of the perl stuff which is needed (and thus taken
    from perl-CPAN) is also available on base/update/dag/dries
    in RPM form.  These are obviously preferred, so
    it would be nice if as many as possible perl packets
    which will later be needed could be installed beforehand
    (still working on this part and minimizing packages
    take from perl-CPAN, is there an auto perl-CPAN to rpm tool?)

I'm sure there's more...
Would more info on any of the above interest you (or for that 
matter anyone else)?

Cheers,
MaZe.
