>From many replies I understand manual thread-joining and -breaking =
exists with mutt's manual commands and default subject breaking -as =
Gmail does- would not be preferred, while not only version control =
systems vary subjects within a thread, but also discussions with slight =
off-topic forks and therefore slightly changed subjects should stay in =
the same thread.

The reason why I asked my question in the first place is because I have =
lots of mail-discussions going on between about 10 board-members who are =
not able to meet in real life often enough to decide everything by =
conference, so our mailboxes pile up with suggestions, remarks with =
longer growing thread-histories and evolving addressee-lists. Those =
addressee-lists vary by individual choice, often without confirmation of =
other participants to involve some new addressee's, sometimes resulting =
in leakage.

I thought to revive mail2forum, a plug-in for phpBB, to force people to =
use existing addressee-lists per 'circle' and archive all =
e-maildiscussions in a forum, so people wouldn't be e-mailed for every =
subject and could lose/drop their own mail. Threads should be compressed =
to keep mostly only original messages - if available -, and small =
citations, or links to original texts if needed. This thread-compression =
is functionality the existing mail2forum doesn't have, so that's where =
for example notmuch comes in.

Discussing around I understand that phpBB misses the very basic feature =
of thread-forking: Every slightly off-topic remark in a phpBB-message =
can only be splitted to a completely new thread.

I wonder whether that is blocking for my own situation, as participants =
in our discussions don't change the subject-line very often, but it =
could probably affect the viability of mail2forum as an open =
source-project.

I don't see how I can easily manually manipulate threads with a mail =
client when mail2forum automatically reads and processes new incoming =
mail, so my efforts with notmuch will probably stick to the 'optional' =
subject-splitting-solution.

As, however, mail2forum should handle postponed e-mail as well (and =
exchange former quotes with their original texts), probably patching =
from a manually altered maildir wouldn't be such a big step. I however =
haven't studied all that's needed there yet.

By the way, before I spend too much time on mail2forum - does anyone =
know an (open source?) group-mail project with user authentication to =
centrally stored messages that already does have satisfying =
thread-compression?
