It's been my experience that when you delete (or move a message to a folder) with IMAP, the server (where your email is ultimately stored) isn't notified of what you did until either your Mail client checks for email again. Once the server has been made aware of what you did, then the next time your other devices check in, they'll get the update (and delete or move the email accordingly). As long as your Mail clients are set to check your email on a schedule, then it should happen automatically. Doesn't mean it'll happen instantaneously though.So anyways, now my gmail is IMAP but I am having problems. First, it only syncs with my iPhone if I actually exit it and re-open. So if I delete an email on my iPhone - the email will still be on my mac mail unless I exit out of mail and re=open it. I want this to happen automatically.
So what happens? Are you getting any error messages on your Mac? With me, the Mail app tends to take the Inbox off-line when that happens. You'll see a funky icon next to your gmail Inbox.Bigger problem - now I can't send and receive email through my mac. The gmail IMAP account downloaded all of my old messages but it will not receive any new emails. I tried writing emails to myself and it worked on my phone but not on my mac.
