getting spam relay using cyrusv2.mc

[corner at chello.at]

Maybe I am not really being used as a relay.  I have now put up sendmail.8.12.9
and it is supposed to deny relaying by default.  Still I am getting a lot of
messages similar to the following:

Can anybody make anything out of this.  Note the subject:
 Undeliverable: Increase your penis size 25% in 2 weeks!

I am really getting annoyed.  Could they simply be using my email address as
the false sender of the message and not really relaying through my sendmail.

Help!
