How to Block/Mark As Spam

[Ax1om]

How does one block or "mark as spam" email messages which contain a particular file extension?

Thank you

I don't think that you can as most antispam programs work on the actual address rather than anything that may be attached to the email.

Only way I found to do this is disable the AntiSpam module. No problem w/me because I have a filter program that lets no email in unless they are already in my white list. ESS was trashing some good emails and couldn't figure out where they were going until spotting a new folder, "ESET Spam" in my Thunderbird folders box. Surprise!
