Hi

My company currently scans emails for attachments but we are considering a change of supplier. of the problems we are having is with allowing users to release their own emails. I've spent a few hours trying to configure it but to no avail and support is only for the configuration, not "how do I do"

Does anybody have any recomendations?

I recommend using a Barracuda Networks Spam Firewall. We have had great
luck with them and they seem to do about 99.9% of the things we want
them to do. They have also cut down on the number e-mails we received
to about 25% of what we had been receiving.

If you have a Symantec Enterprise subscription, you are entitled to
Symantec mail Security for SMTP. Setup a Windows or Linux box, install
the software, and you have your mail firewall. I like this software as
it provides for a central console to manage multiple scanners (servers),
integrates with LDAP, and seems to be a pretty rugged product. The
latest version is a great improvement. The only feature I would
recommend is a per-domain LDAP query instead of a global one. I run one
corporate mail server and use LDAP to block bad addresses at the
firewall, but my lab mail server can't receive any mail as it doesn't
use LDAP.

Clam Av[1] is a free GPL-ed antivirus if you use linux.

A Barracuda might do it, but make sure you look at all their options
before you decide if you want to go with them or not. Me, i think
they lack certain things like prevent certain return messages from
going out, but then I'm picky and can be considered too paranoid at
times
