Q: Can you reply to every email with a "this mailbox is no longer in service" mail? I was wondering if it is possible, in Exchange server 2010, to disable a mailbox account, lets call it mailuser and if anyone sends a E-mail for mainuser@domain.com then it will send a mail back with some sort of standard "This E-mail is no longer in use. Please write to blabla@bla.com instead" mail.
I know I can create an "out-of-office" reply from the users outlook, but it would be so much faster to do it within the exchange server.

A: Check out Hub Transport Rules, there is a really easy wizard there for configuring this.
Hints:
"Apply rules to messages when a recipient's adress contains 'oldemployer@company.com' send 'This E-mail address is no longer in use. Please contact manager@company.com for further questions." to sender with '5.7.1'.
Edit: Just tested it, works just fine!
