Another method is to block executeable content from the web...
Products such as Surf Control can stop users downloading exe's
Also Norton AntiVirus corporate is the only AV product I've found with a
decent network scheduled update......

Subject: [anomy-list]: outgoing email scanning
> Hi there,
> We have been scanning incomming email for a while which has been working
> great and thought that we were pretty well covered as far as viruses go.
> Then the other day we found that a virus had been on one of our
> computers for a few months (we do have virus scanners installed locally
> but the updates weren't working and the user had been too busy to tell
> us that she was getting an error when she tried to update - you can only
> try!) and so we thought about it and realised that if people browse the
> web and use a web based mailer then we have a problem there.
> Anyway, as a result of this, scanning outgoing email has become more of
> an issue for us and so I went through the docs looking to se if it could
> be done with Anomy and saw the section on sendmail saying that there
> might be a description soon about using procmail to scan outgoing mail
> so that it bounces mail back.
> So I guess I'm wondering if this is likely in the near future, or if it
> is possible now and just a matter of nutting out how to do it.
> Thanks for any comments or pointers.
