Recently, I started getting the following error message in Outlook Express
6:

"An unknown error has occured. Subject 'e-mail subject'. Account: 'my
account'. Server: 'my smtp server'. Protocol: SMTP. Server Response: '550.
Tagged as spam. score 10.3'. Port 25, Secure (SSL): No. Server Eror 550.
Error Number 0x800CCC69"

an I am not able to send any e-mails. I am receiving OK.

My AVG antivirus is updated daily and I have checked my PC for viruses but
can not find anything. I also tried turnning off the virus scanner but the
problem still persisted.
I tried creating a new Identity....exported my e-mails from the old identity
and imported them again into the new identity, but ended up with the same
problem....
I still can not send any e-mails.

Please help
Thanks
Aref
