Hi All, I have been facing a problem from 10 days in my exchange server 2007. My exchange server is setuped as followswe have an exchange server 2007 with hub transport server no Edge transport server without ssl. We are using a pop connector to receive all our mails from Godaddy catch-all account to our exchange server 2007. We are sending all our outgoing mails through DynDns MailHop Outbound service. Everything went fine. But from last 10 days I have been facing a problem like, Ex: I have user called test@test.com.When sombody send a mail to test@test.com the user "test" is receiving the mail. At the same time the sender is receiving a Bounced back message like the user "est" with the email ID "est@test.com" ( without "t" from "test") does not exist. the email server rejected the mail. For all the user and for all the senders it is happening like this. Waht could be the problem. Please try to help me to solve this problem.

Hi, Sounds like there is a problem at the dyndns catch-all mailbox. Leif
