I have successfully setup the Droid to download email from (3) different accounts. However, if I delete an email on the Droid, but leave the email on the server the Droid will go and download the email again. This was never an issue on the Blackberry. I typically leave all of my messages on the server so that they are accessible via the web mail client if I ever need them.
Anybody have any ideas how to delete the message so that your phone won't go get it again even though it's still on the server?
