Mail in Snow Leopard has broken. Keeps resending a large file attachment. Make it stop!
Our 2009 iMac running Snow Leopard has hit a snag with mail. After trying to send a bunch of attached photos, Mail stopped receiving messages and continually tries to resend the large message, even though we have done our best to delete it. Even when we do, a few minutes later, it will pop into the outbox again and start all over. We are now using Thunderbird but would like to get Mail back as it has all our organized folders on it. I've called our ISP and the problem is definitely with Mail, not our account. What now?
