April 14, 2011 – We have added some additional blacklists to our normal spam filtering system. Email coming from servers listed on these blackslists will be blocked with a permanent error and bounced to the sender. These emails will not be delivered to our customers – even with a *****SPAM***** tag.
The blacklists we have added are:
UCE-Protect Level 1 (More information)
Lashback
Passive Spam Block List
RATS-Dyna
We hope that the addition of these blacklists will reduce the spam coming in to our users. We take the spam problem VERY seriously and do everything we can to insure that you receive the minimim amount of spam while still receiving all of your legitimate email. If you feel that our new lists are blocking some of your legitimate email, please contact us at 256-547-6817 or email us at support@internetpro.net.
Update: 04/15/2011 – We have removed the Lashback blacklist from our servers. It was blocking Yahoo.com emails which also affected AT&T emails (including bellsouth.net).
We are working to remove Yahoo from their blacklist so we can re-implement Lashback on our servers.
Update: 06/01/2011 – We have removed UCEProtect from our servers because they would not allow us to remove false positives without waiting a week. We have added two additional blacklists to make up for these removals:
Barracuda Reputation Block List
Nix Spam DNSBL – Page is in German
We also added several additional rules to our spam filters to block by content. These included additional filters on foreign spam, scams, viruses, and porn.
