I left off below that I am using
spam-milter 0.3.1-1

================================================== =================

I am new to this. I have been running my mail server in various flavors
for 10+ years. Always trying to do better....

PLATFORM:

Centos 5.0
1Ghz processor 512Mb memory

Mail server: Scalix 11.1
MTA: Sendmail ver. 8.13.8
Spamassassin: 3.1.9
Webmin: 1.360

I followed the Scalix WiKi spamassassin install instructions:
http://www.scalix.com/wiki/index.php...s/SpamAssassin

I am using Thunderbird 1.5.0.12, sending mail has a significant delay.
The meter just sits there near the beginning for quite some time.
Often, the sending times out.

I read through much of the spamassassin WiKi. Nothing on performance
seems to apply. When I go into the /var/log/maillog, I catch soom real
problems.

I enabled DNS checking (dns_available yes) and restarted spamassassin
via webmin and caught the following in the maillog:

Aug 17 12:13:28 z9m9z spamd[1381]: spamd: connection from
localhost.localdomain [127.0.0.1] at port 48800
Aug 17 12:13:28 z9m9z spamd[1381]: spamd: setuid to root succeeded
Aug 17 12:13:28 z9m9z spamd[1381]: spamd: still running as root: user
not specified with -u, not found, or set to root, falling back to nobody
at /usr/bin/spamd line 1161, line 4.

And looking at running processes via webmin I see:

1373 root 12:13 /usr/bin/spamd -d -c -m5 -H -r
/var/run/spamd.pid
1381 nobody 12:13 spamd child
1382 root 12:13 spamd child

What do I change so that it does not fall back to 'nobody'?

Now this MIGHT explain something else I am seeing in maillog:

Aug 17 12:48:16 z9m9z spamd[1381]: mkdir /root/.spamassassin: Permission
denied at /usr/lib/perl5/vendor_perl/5.8.8/Mail/SpamAssassin.pm line 1536

lockfile

Please lend me a hand in cleaning what looks to be a very basic set of
install problems.
