Well, I finally figured out how to add a Yahoo! Mail account to the Android Mail application. There is no need to upgrade to Mail Plus to get POP access, just use the following settings for IMAP:
Incoming mail
Username: your Yahoo! email address
Password: your Yahoo! password
IMAP server: imap.mail.yahoo.com
Security type: SSL
Server port: 993
Outgoing mail
Username: your Yahoo! email address
Password: your Yahoo! password
SMTP: smtp.mail.yahoo.com
Security type: SSL
Server port: 465
The above work fine for me. I have seen mentions on forums to use smtp.mobile.mail.yahoo.com for outgoing mail, but it did not work for me. Strangely, sending/receiving Yahoo! mail only works on 3G connections, it will not authenticate on WiFi. Weird.
