Ok, this is the problem....i have on pop account for lets say user1 and a catch all pop account for user�s 1 tot 10 all on the same domain.

Now if internal user�s send mail to that external user they get it back instantly.
So i guess exchange is not even trying to send the darn message because it is not a user on the server. How can u push the exchange server so that mail to user1@domain.com will be dellivered to the internet.... "[Confused]"

Also how do i get exchange so the message�s with for example 2314321reqer@domain.com (so they dont exist in a user�s e-mail adress) will be routed to the admin box.

You have to tell Exchange that it's not authorative for your domain. If you check your recipient policy you'll see a checkbox indicating something like "This server is responsible for all email to this domain". Most likely you can't uncheck it as it's greyed out. The trick is to add any arbitrary smtp domain, make that one the default, modify the original smtp domain by unchecking the setting (it will be available by now), removing the temporary smtp domain and making the real one the default.

This means that if Exchange won't find a local recipient it will try to send email to whatever server is responsible for your domain according to the mx records (in your case, most likely the external pop account). NB! If your server uses a (local) dns server with mx records that point e.g. back to the exchange server then you must modify the SMTP Virtual Server (or connector if you use it) to use external dns server. See the outbound settings for these objects.

A catch-all mailbox can be implemented in several ways; common options are to configure the SMTP Virtual Server to forward NDR messages to a certain mailbox; use 3rd party software or creating a special event sink in Exchange. See Henriks reply in this thread for some more information: http://forums.msexchange.org/ultimatebb.cgi?ubb=get_topic;f=18;t=000105.

You'll probably get problems if you want to use these features together since the catch-all will also catch any email destined for the non local users as well (which you wanted routed to the external pop account).
