mail message keeps reappearing
I run 2 iMacs with 10.7.3 and Apple Mail. They run on the same wireless network. The mail server is sbcglobal.net. This problem is on only one machine. The other works fine. I tried to send a message with a large attachment (sent the original file instead of the compressed one by mistake). I aborted it when I saw how long it was taking to upload and sent a new message with a compressed attachment. The original message keeps popping up in a "Recovered" mailbox. I delete the message and empty the trash. It reappears within seconds (as unopened mail). I delete it and I delete the "Recovered" mailbox and empty the trash. Within seconds it reappears and recreates the mailbox. It duplicates itself. I also cannot receive mail. I get a perpetually spinning wheel. I can send mail but it takes minutes to go out. I followed the steps in "Mail: Troubleshooting send and receiving email messages" including that I tried rebuilding my inbox.That has been going on for two hours and is still in progress. I rescanned my computer with Symantec Endpoint Protection. Of note, the message I was responding to when all this happened was from a phishing expedition - a friend had responded to a message to "verify" his e-mail address because sbcglobal.net was allegedly being phased out. His account then sent me a request for money because he had been mugged in Europe. I wrote back to him to tell him he'd been hacked and this problem began the next day. This is day 3.
