Sendmail Setup /etc/opiekeys?

Hello all'

I'm trying to setup sendmail on my gateway (dialup) just for sending mail not recieving and I'm able to send mail through localhost and it forwards to my outgoing dialup mail server. Great'

But now I want to send mail from my other computers on the internal network. I added the machine I sending from ( to /etc/hosts and /etc/hosts.allow But I get this message in

Oct 3 15:32:38 localhost sendmail[5885]: OTP unavailable because can't read/write key database /etc/opiekeys: No such file or directory

And in /var/log/mail:
Oct 3 15:36:55 localhost sendmail[5910]: h93MatS1005910: ruleset=check_rcpt, arg1=<>, relay=pluto [], reject=550 5.7.1 <>... Relaying denied
Oct 3 15:36:58 localhost sendmail[5910]: h93MatS1005910: lost input channel from pluto [] to MTA after rcpt
Oct 3 15:36:58 localhost sendmail[5910]: h93MatS1005910: from=<>, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, relay=pluto []

I'm running SuSE 8.2 Professional and Using the SuSE mail config files e.g "/etc/sysconfig/sendmail" and "/etc/sysconfig/mail".

OK' I've done some reading and I'm reading that postfix is a good replacement for sendmail and is getting more widespead. So I'm installing postfix and removing sendmail for now;

I found this rave in a news group:

Sendmail: Is Sendmail
Postfix: Is natively sendmail compatible

Sendmail: Runs as root all the time when it doesn't need to
Postfix: Runs as root to bind to port 25 and as other users to do its thing

Sendmail: Support mbox files. When a single message is corruped, the whole
mbox can die
Postfix: Supports maildirs, though this works best with ReiserFS 9Ext2 runs
out of inodes)

Sendmail: Has legacy crap in it like UUCP
Postfix: Doesn't

Sendmail: Is configured though a conf file so large it is typically editeed
with a macro language
Postfix: Has a small and well commented configuration file

Sendmail: Wasn't written by Weitse Venema, who is God.
Postfix: was.

What do you guys think of those statements?
