Ok. I will do my best to explain here.
I receive emails for multiple projects on the same mailing list.
Specifically, I receive patches for multiple drivers, which are supposed
to apply to different "queue" branches on the git tree. We have queues
for drivers on both net and net-next kernel tree.
The first part of this (unrelated to this patch) is that I combine the
queues, since they are on separate branches, but only affect one driver
in each branch. Basically something akin to an octopus merge.
However, I can't resolve that issue for net or net-next. In addition,
patches include in their subject [PATCH net n/m] or [PATCH net-next n/m]
I have procmail receive the emails, and filter out the patches with net
and with net-next.
Based on this, I use procmail to add a new "To:" address, which replaces
the original "To:". This "To:" is the new aiaiai+project at domain, which
enables me to have the project in the email.
formail's re-write tool, moves the current "To:" which is my mailing
list, to be "Old-To:" so it's fairly standard in that sense.
An alternative, would be instead of replacing the "To:" address, that I
have procmail add an 'X-Aiaiai-Project' header, and modify this patch so
that if X-Aiaiai-Project exists, we use that instead of the project from
the email address.
Basically, I need a way to specify the project that doesn't destroy the
"To:" address. The reason for this, is that I need to be able to still
keep track of the mailing list, as my team wants the replies from aiaiai
to be visible by all the people that watch this list.
