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
/var/spool/mqueue (4 requests)

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

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