Well, right. I block all attachments that have no business being sent via
email, using amavis. If I didn't run my own SMTP server, I'd be blocking them
with procmail.
Here's my list:
qr'.\.(ade|adp|app|bas|bat|chm|cmd|com|cpl|crt|emf|exe|fxp|grp|hlp|hta|
inf|ins|isp|js|jse|lnk|mda|mdb|mde|mdw|mdt|mdz|msc|msi|msp|mst|
ops|pcd|pif|prg|reg|scr|sct|shb|shs|vb|vbe|vbs|
wmf|wsc|wsf|wsh)$'ix, # banned ext - long
I also do greylisting and filter though spamassassin, and use RBLs and a few
postfix tricks. In the past I also scanned all surviving mail with Clamav.
