QUESTION POSED ON: 20 May 2009
Who do I contact to find out if I am blacklisted?

>
One location to check is the MxToolbox Blacklist Check. Another is DShield; while they do not have a blacklist directory they do have a top 10 list that shows some bad offenders. Blacklisting occurs when your mail servers or IP address have been used to spread spam. There are around 100 DNS blacklist databases.
