Exchange server 2000 - spam blocker

[Dthind]

I am not totally sure this is the right place to post this, but I really need some help.

Our exchange server at work is getting hit by literally hundreds of spam e-mails a day. Most of this has been caused by former employees and there is not much I can do about that now.

What programs can I load on the server to reject or delete spam messages. I do not want them to ever see the light of day at an end user work station.

We use active directory services and host our own e-mail server.

Let me know what details you need.

Thanks ! !

I'm not an exchange admin, but I'd like to see an answer for this in case I ever need to use exchange.

And a couple hundred spams is not an issue ... AOL does over a billion a day, and where I work, which is a little, tiny ISP comparitively, we do well over 30,000 a day - or so SpamAssassin+Others tell us.

We receive a few hundred a day with a total number of Visible User around 30. Our Info@xxx.com. Webmaster@xxx.com and Resumes@xxx.com receives the bulk of them.

In case you were not sure, there is this guy in Africa that says I will be paid $100,000 to help him with some stuff, if I only send him $5,000.

Wierd, how I get that 11 times a day from different people...

I did the google search and found lots of Products. But I want something that someone else at least has a little experience with.

Thanks tho..

GFI MailEssentials for Exchange works great. It's simple and straight-forward and you'd probably never even have to open the help-files once to set it up

PC Magazine had a pretty good article on corporate anti-spam tools a few months back. You can read it here. We ended up selecting Ciphertrust Ironmail 210 (Actually, about 8 of them), but we process about 2 million messages per day, so we need big iron (and can afford it).

I use two different filters, one on our mail proxy/relay which does simple attachement and subjectline keyword blocking (Norton AV for Gateway), and the second does attachement and content/dictionary filtering (Symantec AV/Filtering for Exchange 2000).

I block somewhere near 25,000 spams a month here, and people still come to my desk and complain sometimes.

I always show them the stats for the month and threaten to turn off the filters. Usually they get the point; it's impossible to block all spam.

One of the best things you can do is educate your users regarding proper use of thier email address. Let them know not to hand it out on the Web, or post it on message boards, etc..

Alot of our VIPS were getting tonnes of spam b/c thier email addresses were posted on our website in proper username@domain.com form.

Best to use username AT domain . com or something. It's enough to fool the bots.

Dude, CipherTrust looks bad ass. I think I'll have to purchase one for home.
