filter question

[Raymond Orchison]

Hi,

I am running vpopmail with qmail on RedHat 6.1. I have a 2 part question:

1] Is there a way for me to block all mail thar contain attachments with
certain extentions, i.e. .exe, .mpg?

2] If there is a way, how do I do it? Can I block on a per user level and on
a per domain level?

Thank you

Raymond
