System abused by spammer?

Hi list,

I have a vague feeling that some spammer is abusing my sendmail system.

My installation is FreeBSD-CURRENT. Postmaster received some email
saying, that some kind of mail cannot be delivered due configuration
errors. I looked into the mail queue and found this, what definitely
does not belong there!

bsdsi# mailq -v

                Total requests: 4

/var/log/maillog also shows some strange entries:

Mar 28 09:39:59 bsdsi sm-mta[1189]: h2RGCDrC001502:

etc.

I thought, sendmail rejects relaying per default. What can I do?
(HELP!!! (!!!) )

Regards,
Martin
