XP PRO SP1. MS update check says none required.
Suddenly, two days ago, I have not been able to send any emails in Outlook Express.
Typical error msg:
"Error: The message could not be sent because one of the recipients
was rejected by the server. The rejected e-mail address was
. Subject 'Error message for Chris',
Account: , Protocol:
SMTP, Server Response: '550 relaying blocked, read new mail,
add 4.88.78.56 to forwarding or enable smtp authentication
in your', Port: 25, Secure(SSL): No, Server Error: 550,
Error Number: 0x800CCC79"
(I removed email addresses for privacy).
The addresses I'm using are stored and used repetitively without problem until now.
I do receive them OK. I have to use ISP's Web Email service until problem fixed.
ISP says they can't ID a problem. Dial up numbers I use work for them. They suggested virus. I updated and ran Norton Systemworks virus scan and One button checkup.
No change with RESTORE.
Is it truly MY problem or theirs?
