Email setup Q's

[Shrt Bus]

Im trying to setup my email accnts and when going to advanced options there is an option that when the email is retrieved you can either:

Gmail Accnt:

1. Delete off the server or 2. Move it the trashcan.

I would like to know on some ROMS you can leave the mail on the server..and thats what I would like to do.

How can this be done since I only get the above two options???
