Even if it is a nuisance, spam is not a Linux Security issue.
I'll move this thread to say the Linux Software forum.

If SA doesn't find any hooks then you can always blacklist addresses or try to sa-learn it as spam.

Moved: This thread does not contain Linux security issues and so is more suitable in the Linux General forum. It has been moved accordingly to help your thread/question get the exposure it deserves.
