getting spam relay using cyrusv2.mc

[corner at chello.at]

I am having a problem with my sendmail being abuse as a relay by spammers. 
When I installed cyrus-imapd, I used cyrusv2.mc (included with the imapd
distribution) as the basis for my sendmail.cf.  How do I stop this abuse! Help!

Thanks,

Tom Corner
