CentOS docs - Apr 2008 - Postfix pages

First I would like to thank everybody who has contributed to the Postfix 
pages so far. I recently undertook replacing our existing mail server 
(which used the CentOS 4 howto at hughesjr.com) with a new machine 
running CentOS 5 in Xen. The machine is actually running two Xen images: 
mail and web server (the old machine did both functions in one install).
I have done two things that go beyond the existing howtos.
1) I set up OpenLDAP and used it for the database of email users. As I 
see it this has two advantages. From a security standpoint, no user has 
a shell login without any extra steps (I know - this can be blocked in 
other ways). For future upgrades, it is simple to export an LDIF and 
import it in the new machine.
2) I set up MailScanner with ClamAV for virus scanning and Spamassassin 
for spam filtering.
All of this was done with packages from the main repository or from 
DAG's repository, except for MailScanner itself which used the rpm 
installer from their website.
If there is any interest in wiki pages for either or both of these, I 
would be happy to write them.

Hi Michael,

I wrote most of the postfix pages so far, with invaluable contributions 
from others!

As you will have noted, I have tried to keep each guide modular so that 
it may be plugged into a working postfix setup achieved from following 
the first guide. The idea was that users could then pick and choose the 
functionality they required to roll their own custom solutions.

IMHO I think both your suggestions would make excellent additions and it 
would be nice if they could follow the modular approach (so assume users 
have the basic guide up and running).

Regards,

Ned
