Server dying problems

[James Pifer]

We're running MailScanner 4.10-1 and having a lot of problems with the
server dying. I don't know what's causing the problems as suddenly it
will just die. No errors in any of the logs, it just stops. We're
running Redhat 7.3 on a Compaq DL370, 1gig RAM.

One thing we have noticed is that sometimes mailscanner tries to send a
message back to the sender. I'm not sure what cases it tries to do this,
but I think one example is the biggboss.com ones. These messages just
build up in our queue because they can't be sent. Not sure if this is
adding to our problems with the server. Maybe it's wasting a lot of time
trying to send these?

I would like to turn this off. I see Notify Sender in the conf file, but
not sure by the description if this is what I should turn off.

I know I have given very good information here, but if anyone has any
suggestions I would appreciate it.

Thanks,
James
