Mercury/32 Mail Server

I'm having problem receiving mail

[bumpaw]

I installed Apache on an old machine back in August. This is the original thread- [webmasterworld.com...]

Now I'm trying to configure Mercury/32 that came with the Apache distribution, and it is almost there. It can send off the server fine but incoming emails don't see the user account set up for testing. They bounce with:

Sorry, no mailbox here by that name. vpopmail (#5.1.1)

I'm using zoneedit because I don't have a static IP and their test service showed OK for smtp and a pop3 account set up on the Mercury server.

If anyone would have links to tutorials or clues of any kind they would be appreciated. I'm almost there.
