[Esa-l][OT] Attachment blocking

[Andre Kajita - Administrador da Rede]

Greets,

This is off topic to the procmail filter but I guess a few of you may
have thought about this as it is related to email attachments.

The SirCam worm is makeing it's rounds here in my neck of the woods
even with 20 filtered emails in 2 days.  When I checked out WTF some
of our computers had been hit I discovered that they (both of them)
came in through foreign email accounts - most notably Hotmail.

I do have an email attachment policy that is always ignored, no matter
how simple it is - although when one of their computers break due to
an evil attachment they're left computer-less for at least 2 days (my
way of getting back).

What I'd like to know is if anyone has any type of attachment
filtering mechanism for webmail accounts or know of any other way of
stopping these attachments from coming in other than the simple
blocking of access to these services.

Thanks!
Andre.
