Hi, I've been using Mail.app for my gmail account through IMAP since I upgraded to Snow Leopard just over a month ago, and its been working fine. I've found it to be pretty well integrated in general. But today it stopped working completely. Mail opens, but it's not picking up on any new messages I'm receiving in Gmail, and it won't send anything out. I think this might have happened when I mistakenly tried to send a 125MB attachment. I tried to send that, it didn't go through (way too big obviously), and since then I haven't been able to send or receive anything. I've logged out, rebooted, taken my Mail.app accounts offline and back online. Nothing works yet, any suggestions?
