Fed up of Viagra emails

[GaryMurray]

many users are complaining that they are receiving spam emails selling Viagra.

What would be the best method to block them on Exchange 5.5?

GFi Mail Essentials. Or in fact any anti spam product with Bayesian ability.

Just as Zelandakh says, you'll never catch 100% but you will stop the majority by using a good spam filter. GFi is quite well rated.

We use a dedicated Ciphertrust Ironmail here, excellent system and very cost effective.


Carlsberg don't run I.T departments, but if they did they'd probably be more fun.

We also run Exchange 5.5, and found it running rather slow (occasional 30 sec delays, etc). We looked at GFI but did not go that route because our server may be underpowered.
What we did go with was a Barracuda 300. The 300 has one nice advantage over the next model down; it supports LDAP, which stops any mail that is going to an invalid email adr. This means the server never sees it and never has to waste CPU.
The machine gets mail and then sends it to the Exchange server, so the load on the server is much less. Our spam runs about 95% and we were at that level with a little tuning (their user interface is great, very easy to learn!). Their support is very good on big problems, but sluggish on minor things. They have a very active user forum (sponsered by Barracuda Networks), and is extremely helpful.
I probably shaved another 1% off of spam getting through by tweaking other things and doing some keyword filtering, etc, but I think I just caught stuff until the next signature update came out from the Barracuda subscription (the sig can be set to update every hour and works great!)
The slowdowns we see in server response are now mostly gone, the remaining probably due to large file attachments.

I love Xwall.. it sits lightweight on the server. Blocks 95% of spam as well... but does a great job nonetheless.

I agree with Dyadmin. XWall rocks. We've been using it for 2 1/2 years and now have it configured so that it blocks about 98% of our spam. It takes a couple of months for it to "learn" for the Baeysien feature but once its past its learning curve its very low maintenance and very reliable. Excellent support too although after the 1st 3 or 4 months we never needed to use it.

I'm not sure what the pricing is like now but when we purchased it we paid a one time fee of under $500 US.

Cheers.

Best way stop it is to let someone else filter your emails! My company use messagelabs who filter all our incoming emails, and they are damn good at it.

XWall no doubt
