Not too long ago there was a thread sort discussion on the user
list, I have since done a little checking and I like what I have
found. Turns out both Courier and UW (I bet Cyrus does as well)
support thread sort both by orderedsubject (a method of sorting based
on subject content) and by reference ( a line in the headers that
records reply-to message id's ). I will be updating SM's reference
header handling in a few days (hours?) to correctly proccess reply-to
history (thanks Will) which is the first step to allowing thread
sorting by reference. The next step will be a thread sorting function,
either within SM or as a plugin, whatever seems more appropriate.
Even though my role in SM is to work out bugs and refine stable
series releases, I could not resist this one....
Here is a nice reference to thread sorting information
btw, testing a thread sort command with courier from the command line
processed a 350 message mailbox with mail from the squirrelmail-devel
list in less than a second.
Any ideas or comments are always welcome
