  • Catch all mailbox


    We have exchange 2003, running on a Windows 2003 SBS server. This exchange server provides mail for multiple domains. We are attempting to set up a 'catch-all' mailbox for one of the domains. I've followed the instructions provided by Microsoft in knowledge base article 324021

    Having done this the following happens:
    • Internal mail routes fine, even accross the multiple domains the exchange server covers.
    • External mail to valid addresses on the domain with the catch-all work.
    • External mail to invalid address are not routed to the 'catch-all', and return a 550 5.1.1 user unkown message to the sender.
    Does anyone have any idea what setting / settings we need to change to get mail sent externally to route correctly to the catch all mailbox?

    Many thanks in advance.

    Catch Alls should be avoided at all costs. They are nothing but a spam trap.

    All of the Exchange methods are kludges which don't always work very well and often cause more problems.
