here is the situation:
Small Business Server 2003, Exchange 2003, E-Mail is retrieved through POPcon a connector that connects the e-mail boxes in the datacenter and then transmits these to exchange.
Since some internal users prefer to access their e-mail through the data-center postbox e-mails need to be received on both the exchange server and the data-center postbox
E-mails that come from an external domain i.e. extern.com work fine. Yet when a user of the company email@example.com sends an e-mail the e-mail is routed directly to the exchange server and not to the external smtp server.
What needs to be regarded:
I know that I could set up E-Mail forwarding, yet this would cause the user to have the e-mail twice in his postbox on exchange since the popconnector would retrieve the mail from the data-center again?
