I'm not really sure when this happened, but today I noticed we were on the Spamhaus Whitehat Network, which indicates we are a proactive no-spam-tolerance network. I appreciate the recognition, as we do try hard to do our part in preventing spam, though most of the credit for that should go to Kevin, who has done a marvelous job managing our abuse department.
Now hopefully the spammers won't even try to sign up for accounts with us, though I doubt we will be that lucky.
Note: If you are looking to cut down on spam, simply using the Spamhaus RBL's could be an immense help. Spamhaus is our pick as the most trusted RBL available as they are very intelligent in their listing, for the most part, and give reasonable methods for list removal.
