Ok. We got it working.
We are using a different email address system than yahoo.
Our incoming server is normal: pop.myisp.com
Our outgoing server is smtp.mail.yahoo.com on port 465 and using SSL
We also have to use the outgoing server requires authentication.
So we used the the email address for the user name and password for the
password.
Thanks for your help.

Found out we are using sbcyahoo internet for the connection.
I'm going to contact them to see what about authentication.

AT&T is in the process of changing SBC Yahoo to SSL connections and the
ports for POP and SMTP are changing to 995 and 465, respectively. The
servers are changing as well from pop.sbcglobal.yahoo.com and
smtp.sbcglobal.yahoo.com to pop.att.yahoo.com and smtp.att.yahoo.com. You
should have received a message about it in your SBC Yahoo mail. They also
provide a migrator tool to allow you to update all of your account
settings. See http://helpme.att.net/article.php?item=10918
