I am afraid there is currently no solution that will work in all cases, since 
neither  the task list nor KWin export the necessary internal functionality 
over DCOP.

It might be a matter of setting a different "Focus stealing prevention" value. 
KWin tries to keep new windows behind the currently active (focused) one, 
unless the new window is related to the active window (for example a dialog), 
in order to avoid that the user enters information into the wrong window, or 
triggers keybord shortcuts there.

A program supporting single instance through multiple starts, such as 
Thunderbird in your case, might have optional commandline arguments to force 
a window raise.

If an application does not support single instance behavior, in your case this 
seems to apply to Evolution, it will be started a second time.
Of course the program could also have a commandline switch which is indented 
to just pass the parameters to an already running instance of itself.

Cheers,
Kevin
