Default 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
