Outgoing Email Connection Error

Go to application-> Email-> Hit menu button on the far left bottom-> Account settings.
Under Server settings, go to
1. type in your user name (yourusername@yahoo.com), password, IMAP Server (imap.mail.yahoo.com), port (143), Security Type (None), IMAP Path Prefix (Optional), and hit next to continue with SMTP Server.
2. type in SMTP Server (smtp.mobile.mail.yahoo.com), port (587), security setting (none), check on require sign-in, username(yourusername@yahoo.com), password, and hit next.
That's all you gotta do.

Well it is a bit more complicated.  I have a Yahoo account but my email address is graceg@pacbell.com.  Also, when I go to try to change the setting, it is currently set to pop3 server pop.pacbell.yahoo.com set to port 110.  It is working for incoming. I don't know where imap input is.  The outgoing is set just like you suggested with the exception of smpt.pacbell.yahoo.com.  Any other hints?  Do I really need to change the incoming settings when it is already working?

Thanks

Thanks.  I will.  I actually meant pacbell.net.  I almost want to start all over, but don't know how to uninstall it.  I may just use my gmail account and have all my Yahoo mail sent to gmail.
