  1. From a Mailblocks customer.. by VudooCrush · · Score: 0, Troll


    I am very happy with Mailblocks' challenge-response system. Their webmail based system is blazing fast and just plain works well. I can drag and drop emails to different folders, etc. The account is also a regular IMAP account so you can just pop their settings into your regular email client. However, a couple of companies ( namely some online casino and 1-800 Flowers ) managed to get through the challenge-response. I have a hard time believing that someone from 1-800 Flowers waded through all of the bouncebacks and performed the challenge response. It's very possible but not likely.. So that sounds fishy to me. I hope they stick around, I really like the service. Having a really fast/cheap 50MB IMAP account that I can check from anywhere with a web browser is pretty slick.
