It does not work for me, and other two N900 device Ive tested:

Follow this instruction to set up your Yahoo! Mail imap 4 account on your N900:

Email - Menu - New account

Next

Region: select your country or leave it on default

Service Provider: Yahoo! Mail (not Yahoo UK and Yahoo Plus!!!)

Next

Username: your account name at mail.yahoo.co.uk

Password: your password

Email address: youraccount@yahoo.co.uk

Finish


After this I always receive IMAP4 account settings window with incorrect username/password

Am not stupid and idiot, I use daily my yahoo account. IMAP4 setting is works on other devices except on N900.

It was tested on 3 different N900 device with 3 different Yahoo Mai account! It does not work. :-(

And I wont use a payware nokia messaging service, so do not offer that to me, thanks! ;-)

Please, help me to debug this error. Thank you!
