Jabber and Proventia G

Hey there,

I need to know how I can block jabber users from sending
attachements.

We are using a jabber server just like http://status.jabber.org and
the clients are win32 using the jabber app we can download there
www.neosmt.com

I've been looking and I do not know how to write a policy for
Proventia G.

The general idea is to block known potential threads like .exe, .zip
or whatever like that. If it is a .doc, .xls or PGP encrypted files,
I need it to get to my mailbox. Also, I can send a JPG file which is
in fact a renamed PDF.

The users are using Jabber in clear-text but in the future we may
enforce the use of SSL.

How do I do it?

Thank you very much,

Allan Setright
