I am new to KDE. I have Kubuntu 13.04 installed on my desktop.
I use 2 emails - YahooMail and Gmail. Yahoomail is my default email.
I need to know how to configure Kontact and Kmail with Yahoomail and Gmail. I required both of them. I tried to configure both. I successfully configured Kontact with Yahoomail and i can also send emails using that. But, when I configured Gmail, I am not able to send mails from Gmail.

Is there any way of resolving this.

Also I have a query about Akonadi. How to use Akondai. What exactly is the use of Akonadi with Facebook, notes, calender, SMTP, POP, etc..
