dont inform senders via mail about spam and virus invents
this leads to backscatter, cause mostly sender addresses are faked.

A short message in smtp reject code , if you are brave enough to reject
mail about classified by your antispam, may be ok.

If you have urgent need to make someone notice about spam or virus
envents via mail inform the reciepient and/or the postmaster
