First of all we need to know both your incoming and outgoing mail servers, which may be different in certain cases.

Focusing on your only issue to send email, let's see how my "Sending Email" tab in the "Account Editor" window looks like, as shown in the next screenshot:

enter image description here

As you can see, my "Server configuration" reads the outgoing server's name plus the port after the two points symbol.

Additionally, Port 587 may require authentication based on your email's name and not just your nick and make sure you don't need to use a encrypted secure connection.

Give this a try and please inform on your outgoing server's name in order to change this answer if needed. Usually, doing what I mentioned here fixes that issue.

Good luck!

The day before yesterday (March 21, 2013), evolution both sent and received mail from without a hitch. Yesterday it failed to send. I found this thread and a few others looking for an answer, even tried Thunderbird (which did work). My eventual solution was to turn on SSL encryption for sending. It was already on for receiving.
