I wanted to ask if anyone has hints about how to install Postfix such that grief doesn't ensue.
Currently, my config / issue is thus:
-CentOS 4.3 32-bit Hardware host platform
-Latest OpenVZ Stable kernel installed, running
-CentOS "Default" 32-bit (or "minimal") Virtual Host Environment
If I create a clean virtual machine, then install postfix and use "system-switch-mail" to disable sendmail / enable postfix..
Postfix seems to be having trouble because in the config is an option which specifies what interface to listen on. By default it is "localhost". I've tried changing it to
lo
venet0
venet0:0
and also tried adding entries to /etc/hosts for the above .. to reduce complaint from postfix when I do a "service postfix stop ; service postfix start" in the VZHost.
Alas, I get interesting results:
(1) Postfix is pissed off
(2) My interface falls off the map, ie:
BEFORE postfix is running:
---paste---

(note "X" is added to make my IP private here in the posting, it is a regular number "for real"...
AFTER postfix is running:

-bash-3.00#
ie, no IP associated for venet0:0.
Ugh!
It strikes me as particularly interesting that postfix not only chokes, but kills the interface as well.
If anyone has comments on this, it would be greatly appreciated.
Many thanks,
