SMPT Filters

[mjack@xxxxxxxxxxxxxxxx (Mark Jack)]

I have been following the discussion about filters and it has been very helpful in stopping spam to my accounts. I have a question that I have not been able to find the answer to. Is there a way to setup a filter to filter out executable attachments...  Like .exe or .pif
If so how do you set it up? I have an account that is being sent a lot of emails that have an executable attachment that is a virus or at least the virus scanning software thinks so. I have tried to set up a filter in the past but it didn't seem to work. I have also checked the logs but these emails are coming from various accounts so trying to block the IP would be difficult. Right now Post.Office doesn't have virus scanning ability so some sort of filter to stop these attachments would be nice.

Regards,
Mark
