I have outlook express 6 and Windows XP SP2. Starting yesterday, I get an
error message when I try to send an email. It says that host has been
blacklisted by cbl.abuseat.org. There is a server error 550 and the error
number is O or 0 followed by a multiplication sign followed by 800CCC79.
I haven't a clue; can anyone help, as I can't send any emails?
Thanks
