Forwarding to Gmail

I configured a Dreamhost email account to forward to my account AND also deliver mail to my Dreamhost mailbox.

While I was logged into the control panel today, I noticed that the settings for my email account seemed grossly incorrect, yet mail seemed to be forwarding to and also getting delivered to my Dreamhost mailbox.

On the “Addresses” screen, the panel shows that my Dreamhost account ONLY forwards to some address I have never heard of. When “edit” the Dreamhost account, no mailbox is selected and again the mysterious account is set-up for forwarding.

Any ideas what might be going on here?
