i'd like a mail app that will log on and download new messages without looking through every single one of my emails on the server, new and old. Specifically, i have a Yahoo account w/ 700+ emails and the mail app would log on and download them all. I had hoped it would do this only once and then download news ones going forward but after downloading 700 emails to the Axim and then deleting them and then logging on again to download new messages, it would download them all again. it was essentially syncing to my yahoo mailbox instead of simply downloading new messages.

i feel like i'm not explaining this well.

anyone have any thoughts?

thanks in advance,
mark
