Thank you for your inquiry the Five Ten Blacklist, we greatly appreciate your feedback. We do receive quite a number of complaints about certain Blacklists but keep in mind that we do not manage any of the Blacklists, we just provide a look up tool. We do not recommend blocking mail based solely on the data from any Blacklist as these lists should be only used as a gauge to determine whether to consider a message as possible spam.
If you are having mail delivery problems due to any Blacklist, we would NOT recommend their fees for expedited removal. This payment does not determine if you are listed again or have other problems with Blacklists. If a Blacklist decides that they would like to charge money for expedited removal from a service that it runs with its own resources on its own time, then that is their choice.
If we were to remove any of the Blacklists, then those that are listed on a list may not have another resource to identify these problems.
However, given the nature of the blacklist that you are appearing on, you will not be able to delist your IP address as long as it in this block of IP Addresses. This is a problem with your ISP, and can only be resolved by working with them to unblock or to move your domain to a different server, or reassign a new block of IP Addresses.
I wish you the best of luck in getting your problems resolved. As always I like to make sure that our visitors are aware that in addition to our free tools we also provide paid
Products which can alleviate both your outbound delivery issues as well as provide
inbound spam and virus protection and
email continuity for emergency situations as well as
hosted mail.
