In the Incoming mail (POP3, IMAP, or HTTP) server box, type "pop.mail.yahoo.com"
In the Outgoing mail (SMTP) server box, type "smtp.mail.yahoo.com"
Click "Next."
In the Account Name box, type your Yahoo! Mail address (without the "@yahoo.com").
In the Password box, type your Yahoo! Mail Password.
If you want Outlook Express to remember your password, check the "Remember password" box.
Do not check the "Log on using secure password" box.
Click "Next."
Click "Finish."

Hmm, I just tried that and it didn't work. I use a separate hotmail account and it I assumed it would work the same.
Okay this is what you do. Either set a separate identity and switch users or create message rules (email filters). You can create subfolders and set all of your yahoo pop mail to filter into the appropriate folder.
Blah, Blah Blahh, Blahh, blahh blah blahh, blah blah.
