Spam Filtering Statistics

June 12, 2010 in Smile News by admin  |  Comments Off on Spam Filtering Statistics

Just a few numbers from some preliminary testing we’re doing on the spam filtering, with the combination of selective rDNS lookups and message scoring.

The selective reverse DNS filtering is blocking around 100 messages a minute, or almost 2 messages a second. These are send by infected computers around the world.

In addition, the message scoring system is deleting about 30 messages a minute, or a message every 2 seconds.

In addition to these spam blocks, we are also graylisting mail, tagging suspected spam, and checking various spam blacklists.

Please let us know how the filtering is doing by sending email to support or submitting a trouble ticket, at
