Everyone seems to be up in a tizzy about Mailblocks selling out to AOL and discontinuing the service. I believe if you do a little of research you will find that
Mail-Block was doing business before Mailblocks came on the scene.
I have used their service for the past 3 years and in my opinion the verification process for people sending to my account for the first time is much easier then what Mailblocks used. For anyone that is wanting to check this service, there is a site where they allow a free 30 day look (without having to submit payment info). This appears to be an arrangement with Bright House Networks for their customers. The only difference that I can see is that there is a subdirectory added to the regular service
cfl.mail-block.com
