Hi All, After long googling, got my yahoo mail(Free account - IMAP) working on N900... First create and signup for a Nokia Messaging account.. On N900 click E-mail in the menu Create Nokia messaging account first with the "New Account" option. Region : India Service Provider: Nokia Messaging then click next User name: XXXX(nokia messaging username) Password ; XXXXX(nokia messaging password) Then it connects with service provider and in the E-mail tab you can see NM account created.. Now Edit the Nokia messaging account.. Goto Mailboxes, then Add Mailboxes(Click) Now its possible to create the accounts... Since Gmail is easily created and has an inbuilt gmail account, am not specifying the details... Creating Yahoo Mail (Under NM --->Add new mailboxes) Create all the credentials Account title: username:XXXXXX(Your yahoo user name) password:XXXXX(your yahoo password) Email address: XXXXX@yahoo.com(Yahoo mail i.d) Incoming Server : imap.n.mail.yahoo.com Secure authentication : unchecked Port : 143 Outgoing server: smtp.mobile.mail.yahoo.com Secure auth: none port:587 Then Save... Now you can see Yahoo mail in the Main E-Mail Tab, below or above Nokia Messaging. Now from the drop down tab in the header area, Click Send and Receive.... Yahoo mail and Nokia Messaging Sync's with their corresponding server... In 5-10 mins, you will find Yahoo mail boxes and new mails will be updated... If not, Reboot your mobile and Sync it.... It's working fine for me.... Hope it satisfies the needs of many N900 owners...
