sync sent mail between iPhone and mail.app Can I set up my mac/iPhone/mobile me to sync the mails I've sent on my iPhone back to my mail.app on my mac?

I use two email addresses: an IMAP (gmail) address and a microsoft exchange address.

On the other hand, I can't even see the mails I've sent on my iPhone in the mail app on the iPhone, it only shows mail.app sent mails.
Solution for Gmail:
Gesendet must the the label of the mailbox that you use for sent mail on the iPhone. (info: gesendet is German for sent)
I believe the default label is named Sent Messages created once you set up Gmail on your iPhone using IMAP.
