Email filtering and protection Help

Today we use Postini for inbound email protection.
Today we use Symantec's SMTP Gateway (running on Solaris) for outgoing email
filtering. (helps stop bad stuff from our customers sending email to the
Internet) This SMTP Gateway software is "End of Life"

Does anyone have recommendations for other products/software to filter our
outgoing email, from our customers going to the internet.

Thanks,

Are we talking virus protection ?

You might want to look at something like amavisd-new or clamav in
SMTP proxy mode.

http://www.ijs.si/software/amavisd/
http://www.clamav.net/

Amavisd-new together with clamav and SpamAssassin will block a big
chunk aof spam and viruses.

Some vendors like Barracuda and IronPort do this as well, if you're
willing to pay.

Cheers,
Phil

For Roll-your-own it's hard to beat a combo of MIMEDefang/SA/Clam (MD is a
milter, so sendmail or postfix needed).

The MIMEDefang developer also started a company which sells CanIT Pro, an
appliance version of the above with additional features/web
interface/support

Ironport (reassuringly expensive) has worked great here at work.

Postini also does outgoing email filtering. Just requires setup.

I (we) use SBG, if you like the Symantec stuff it is much better than
the SMS SMTP product.

Based on the amount of spam their customers send me, it doesn't
work very well.
