Paul your right..
Thx for the tip..I figured it out 1/2 hour after posting...Its weird but I didn't fillout the authentication l/p in the fields but when I did it..It still didn't work..So I trashed everything and started from scratch, then finally, I can send.....For the other person that has a prob...Would this help? ( I know its Yahoo's but..It might help):
In order to use an email client to send and receive Yahoo! Mail messages, you must designate a new incoming (POP) mail server and a new outgoing (SMTP) mail server.
If you can't add new POP or SMTP servers, you'll need to change your current server settings. Before you change anything, write down your current settings -- you may need to revert to your original settings later if you decide to send and receive messages from your other email addresses.
Here are the basic server settings for Yahoo! Mail:
Incoming Mail (POP3) Server:
pop.mail.yahoo.com
Outgoing Mail (SMTP) Server:
smtp.mail.yahoo.com
Account Name/Login Name:
your Yahoo! Mail name (your address without the "@yahoo.com")
Email address:
your Yahoo! Mail address (i.e.,
user@yahoo.com)
Password:
your Yahoo! Mail password
