Is there any more to the error message?

Yes, a long message about the outgoing smtp name not matching with imp name,
I believe. But, I won't know until I'm back at work on Monday-

My error message reads:
The message could not be sent because it rejected you as the sender. Server
response:"505 MAIL FROM sender and AUTH username do not
match'.(Account:'imap.aol.com', smtp Server:'smtp.aol.com', Error
numberx800ccc78).

You're sending to an AOL SMTP server but are you sending AOL mail?
