Default Sent email rejected

Peggy, it is funny that your "unchecking" and my "checking" both worked. Is
Comcast your ISP? bw

Bob, I have had the exact same problem for 3 days now. I just went in and
UNCHECKED "My Server Requires Authentication" and all of my outgoing mail
just left! Hope it works for you too.

Outlook Express has been used for a long time with no problems and nor
alterations have been made. 4 days ago the sent emails were rejected. I
turned off computer over night and it worked again the next day. Then,
yesterday, the sent emails were rejected and I shut off computer overnight.
Error problem still exists. Receiving emails works OK. I can send OK
through webmail at Comcast, but not from OE. Here is the Microsoft error
message:

The message could not be sent because the server rejected the sender's
e-mail address. The sender's e-mail address was '.
