Mail on my MacBook pro not working
My mail account on my 13 inch MacBookPro has stopped working and I am out of ideas.
I can receive my mail on the iMac, the 15inch MBP and on the iTouch, synchronization is working and I can also receive mail via MobileMe.Also my wife using all the above also can send and receive mail. the Internet work on all machines.
The problem is isolated to mail account on the 13inch MBP. This was working until last night when I attempted send a very large file and half way through the message said can't send it via the server and I stopped it and deleted the outgoing message. I seem to recall that I received and sent messages after that.
I have rebooted and restarted, checked the settings with the iMac and the other MBP, all are the same. I have re set the modem. Also sent messages back and forwards via my wife's e-mail on the 13inch MBP and the iMac. All sent and received ok by the other units. I have sent messages from my account to my wife and myself from the imac. Received on iTouch, Mobileme and my wife's account ok.
The problem is isolated to the 13inch and the mail programme.
The 13inch MBp has a continually spinning wheel or the bell,( seems to alternate) and a file "on my Mac" which shows numerous times a message from me at 7.27 last night with no subject. I have no idea what that is.
I hope that this gives enough info to someone to point me in the right direction as to how to reset this machine and get the mail working.
I appreciate any assistance.
Thanks everyone
