error 0x800CCC78

I have looked on this discussion group but have not yet been able to solve my
problem: Each time I send and e-mail (new or reply) I get several of these
error messages. The mail sends eventually but takes a while to exit the
Outbox.

Task 'yahoo - Sending' reported error (0x800CCC78) : 'Unable to send the
message. Please verify the e-mail address in your account properties. The
server responded: 553 From: address not verified; see
http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html'

I sent anote to Yahoo but no reply. I do not know why yahoo is involved
except for...my mail is rerouted from an sbcglobal.net account to my Outlook.

Any ideas for solution? I disabled COM add-ins and my "From" address looks
fine.
Thanks.

You are an 'at&t Yahoo! HSI' customer. If you use the STMP message
submission servers normally given to such customers, you *are* using Yahoo!
servers; 'smtp.att.yahoo.com' belongs to Yahoo!, not AT&T (which is the new
name for SBC, which bought AT&T effective Jan. 1, 2006).

You can have up to 10 sub accounts on a Primary account. If you are logging
in to 'smpt.att.yahoo.com' with your Primary account log in, but sending
from a sub account, Yahoo! does not know that the two email addresses are
associated (only AT&T knows that). Consequently, under new rules implemented
by Yahoo!, your connection is closed with error.

There are two solutions. The weaker one is to log in to
http://mail.yahoo.com/, using the same username+password you use for the
SMTP log in. Go to the mail options link, and add your sending email address
to the list. The weakness of that solution is that you must do that for
every email address you use for sending; and Yahoo! will only verify ten
additional email addresses.

The stronger solution is to switch to one of the legacy AT&T Internet
Services run SMTP message submission servers. If your email address is in
the 'sbcglobal.net' domain, you could use 'mail.sbcglobal.net'. For now,
that one does not require authentication. That may change shortly, however.
Or use 'smtpauth.sbcglobal.net', which does require authentication.
