I can receive email, but not send email. Although I can send emails to myself.
I didn't change any settings today. It just started to happen.
I get this Error Message: Cannot send message using the server.... Send the message content to the server failed.
I can send emails to myself. Is this a clue to anyone?!
I called my ISP and troubleshooted. No luck.
With Connection Doctor, I'm able to connect to the server.
I upgraded from 10.6.2 to 10.6.8 and no luck.
I deleted thousands of emails in the SENT and JUNK mailboxes and no luck.
