Deleting pop3 emails

[russmd]

I had an original Droid. When I downloaded POP3 e-mail to my PC (and it deleted from the server), the downloaded POP3 e-mail would automatically delete from my phone the next time it refreshed. I liked it that way.
Now, on my Droid Pro, the POP3 e-mail remains on the phone depite it being downloaded to the PC and deleted from the server.

Is there a way to get the phone to reflect only what is on the server like it did with my original Droid?

Thanks.
