Postfix or Exim?

[mdevin <mdevin@ozemail.com.au>]

Look, I know this is a flame bait question.  I was interested in trying
Postfix because I thought it may be more customisable and easier to set
up.  However, I had trouble getting it to work because it complained
that port 25 was already taken:
postfix/master[1011]: fatal: bind 127.0.0.1 port 25: Address already in
use
I think this was due to inetd binding this port for some reason.  I had
upgraded from Exim and it was gone and there was no other smtp daemon
running.  I didn't try telnetting into port 25 but I did comment out the
smtp part in inetd.conf and it still wouldn't run.  I also checked with
ps aux and there was no hint of exim.

So my question is, should I bother with postfix?  Is it easier to
customise, edit headers etc?  Is it more robust?  What are some of the
advantages that made some of you change to postfix?

Regards.
