First, you should send yourself a message to test your
configuration. To send a message, either hit Ctrl+N, select the
New Message icon or select
the Message->New
Message... menu item. The
composer window will appear. Fill in the
To: field with your email address and type
something in the Subject field. Send the message by
selecting Message->Send.
To check your email, select
File->Check
Mail. In the lower right corner of the main
window, a progress bar will indicate how many messages are being
downloaded. If you receive the message you just sent, then
congratulations! If, however, you receive any error messages while
testing your setup, make sure that your network connection is working
and recheck your settings at
Settings->Configure
KMail....
