Initial implementation completed.

Sure. The idea is to have a link "View thread" in the message view 
that shows the content of all messages of the thread this message 
belongs to. I think Gmail has a similar feature now.



There are probably a lot of ways to implement such a feature, but I 
thought the easiest and fastest solution would be to get all messages 
from this thread, construct a single multipart message from them and 
render the result with the regular multipart mime viewers.



I am not sure what state my patch had when I worked on it the last 
time, but IIRC it only showed the headers of the mime parts (single 
messages), but not the bodies and I wasn't able to find out why.

What exactly are you shooting for here (i.e. could you provide a bit 
more of a description of what needs to be accomplished?)

I started implementing a feature a while back that allows to view the 
complete thread of a message at once. Unfortunately this didn't work 
as expected and I'm having a hard time to find out why. Maybe someone 
else (Michael? :-)) can see where I stuck.
