[plug] Help with spam

[Brian Tombleson]

You are probably open to relay.

Have a look here: http://mail-abuse.org/tsi/ar-test.html and test your
system by following the instructions.

You didn't include your sendmail version in your question, but if you
upgrade to a more recent version of sendmail (8.9 or above) it will have
relaying denied by default.  This is recommended.

Check out www.sendmail.org (particularly the FAQ and the "Tips & Hints' at
the bottom) - It's all worth the read.

Hope this helps.
