We sampled 1 days email (20 hrs) to see how it was performing – and the figures are amazing. Over 24000 emails hit our server, of which only 8% were legit! so over 22000 emails were junk – with the MPP filter blocking RBL (black list), Commtouch traced spam and ClamAV ID’d virus’ at the front door of our sendmail box. Some were rejected, some sent to SQL quarantine, and some passed through with no noticeable affect on the server boxes performance.Its incredible to think what end users would be getting in their mailbox each day if MPP wasnt there protecting the system.

MessagePartners MPP eMail server security is the product we use for our mail server. It protects our internet customer base from spam and virus’ before they even get to their mailboxes – keeping them free for the good stuff to make it through.

We initially ran MPP with SpamAssasin, a free anti spam engine that worked well, but would only get about 60-70% of the spam coming in (which was a major improvement over 0% which is what it was!).

We then looked at upgrading to a commercial engine – and went with Mailshell. Another major upgrade, which got us up to about 85% stoppage, but with a few emails starting to get false positives. Its always going to happen thanks to the many and varied ways spammers try to get their junk out!

Just recently we went to one of the premium anti spam engines (Cloudmark being the other one) called Commtouch. And i have to say the spam recognition is now around 96-98%, with virtually NO false positives! Our customers are getting the advantage of only real mail coming in, and our mail server is not overloaded with junk. It only costs a few dollars more per year for each mailbox to have the premium engine, but it was worth every cent. It is becoming a strange expenrience to check the mail each day and find its all real – something I havent seen in a real long time!
