Did you ever heard blackberry or push mail? Now you can have it for free on your nokia E series (I don't know it is applicable for different series or not). Ok, I will explain it step by step :
1. You must have Mail for Exchange (download it at
http://www.businesssoftware.nokia.com/mail_for_exchange_downloads.php)2. Install it on your phone (mine is Nokia E61)
3. Sign up email to mail2web.com
https://services.mail2web.com/signup/mail2weblive/mail2webLive_01.asp . Why mail2web? Because mail2web is a free email service based on Microsoft Exchange. And we need Microsoft Exchange based server for push email.
4. Set up your Mail for Exchange on your phone. Server (mobile.exchange.mail2web.com), domain (ad2), and for example, you can see this picture.
5. An even minor complaint was that I kept on forgetting to log on with my
FULL @mail2web.com’s email address. I tried just using my registered
name without the @mail2web.com part, but that didn’t work. So save
yourself some trouble and remember to use your FULL email address when
you log on to the services.
6. Warning!! Back up first your phone. In case do you have a trouble, yau can hit back your phone with your back up.
