[CLUE-Tech] Mail issue

[black at galaxy.silvren.com]

You guys seem to be pretty affluent with mail issues, so I thought I'd
throw mine in:

I have two linux boxes, one using slackware 9.0 and the other using redhat
8.0. Both are running default configurations with sendmail, with the only
exception being I've edited the config file to specify a relay.

So, the line looks like:

==================
# "Smart" relay host (may be null)
DSmy.relay.com
==================

Obviously I've changed the actual DNS name I've stuck in there.

I'm running Snort with ACID on both these peecees. Within ACID I have the
option to email myself alerts. When I try to email them, only the mailings
from the slackware box make it. The ones from the Redhat box don't.

They both look like they should work. Any ideas on where to start
troubleshooting this issue?

Thanks
