I created a new user (ad) and I did the wizard to create a exchange mailbox. I just have a problem that I can't receive mail from an extern email adress, mail from other mail adresses on the server is ok, and I can also send mails. Just the one that's quite important that I can't do. When I send a mail to the adress, the MDaemon from the domain sends a mail with the message Warning: No addresses survived parsing process! The attached message doesn't contain any addresses that can survive the current parsing configuration. Does someone know what I can do to fix this.???

Seems like an issue with the MDaemon of the domain, not with Exchange. Never heard of this errordescription.

I have looked up some help for you try http://www.altn.com/Support/KnowledgeBase/KnowledgeBaseResults/?Number=KBA-01322 or: maybe not
