thank you for your help really cant work out why this has stoped working

In Mail under preferences under accounts check outgoing mail server (SMTP) and make sure your
setting is correct.

i delte my gmail acount and re added it to to mac mail and it seems ok now


it seems the out going sever had been deleted or stop some how but its all working now
