Problem sending e-mails with Outlook & SBC Yahoo DSL

[SBC Yahoo DSL customer]

I have been unable to fix a problem and am looking for
help. I have Outlook 2000. I also have SBC Yahoo DSL. I
have spent hours on the phone trying to fix this problem,
reloaded my software, etc. I can recieve e-mail from the
SBC Yahoo DSL server with my Outlook, but cannot send e-
mails. The error message I get is 0x800ccc0f. I know this
means the outgoing mail server does not recognize and log
me in, but does anyone know a way to change this? SBC made
sure my settings were correct, but the problem persists.
They claim it is an Outlook problem, but it never happened
with other ISP's. HELP PLEASE!!!

In your e-mail client, do you have it authenticate to the outgoing
(SMTP) server (by providing username and password)?

The error message would show more than just an error code. It might
help if you post the complete error message here (but munge anything
sensitive to prevent misuse of your configuration or account).

Do you run a software or hardware firewall? A router with a firewall?

Do you have anti-virus software installed to scan email? If so, try turning
it off to see if it might be the problem. If it is, see if there's an
update from your anti-virus vendor that will correct the problem.
