The IMCEAEX part is what's called an encapsulated address. It looks like the POP accounts (I assume you mean Exchange mailboxes accessed via POP3) have not been properly replicated to your site (Exchange site, that is). If you run up the Exchange Administrator on your site, can you see the POP accounts at the other site?

We are running exchange 5.5 sp4 win2k box. We have 2 exchange servers in different locations both in the same organization the company is split into 2 locations one server at each site. Our server receives SMTP mail via our router; the other site uses pop accounts for email. For some reason our mail server is sending our domain name on all of the pop mail accounts and this is causing problems for the users.
