[gentoo-user] OT - Mail question

[Michael Sullivan]

What do you make of this?  I found it in /var/log/messages:

Jun 22 10:59:15 bullet sm-mta[2558]: k5L4mNFw021664:
to=<aw-conf@midamerica.com>, delay=1+11:10:52, xdelay=00:03:09,
mailer=esmtp, pri=6425885, relay=mail.midamerica.com. [65.243.220.163],
dsn=4.0.0, stat=Deferred: Connection timed out with mail.midamerica.com.


There are several of these.  It looks to me as if someone is trying to
send mail to aw-conf@midamerica.com, but neither my wife nor I know
them, and we're the only espersunited.com users who use mail actively.
Has my mail system been compromised?

The mail in question is still lying around somewhere under /var/spool 
(depending on the MTA you are using). Find it and read it with an editor. 
That might give you a hint what is going on.

Also, read your MTA's log file to find out who has sent it.

I found something that suggests that MAILER-DAEMON is trying to email
aw-conf@midamerica.com to tell them that their spam has been rejected.
Probably sent by Mailman.  If I can find the original email, can I delet
it and make sendmail stop trying to send it?

I haven't used sendmail in ages (about 10 years). I don't remember how to do 
it cleanly.

Why don't you move to a modern MTA like exim, postfix, qmail or such?

Hi,
Are you using a local mail-server or a relayhost (yout ISP mail-server)?
Check to see if your mail server (if any) isn't an open relay.
Google for a site to check or check the config.
