I'll do. In the mean time, please have a look at b4, it has support for
sending patches via a web hook.
Hooray for switching to b4!
Yes! Unfortunately one of the most relevant features does not work:

$ b4 prep --auto-to-cc
Will collect To: addresses using get_maintainer.pl
Will collect Cc: addresses using get_maintainer.pl
Traceback (most recent call last):

$ b4 --version
0.14.2

While get_maintainer.pl itself works ...

$ scripts/get_maintainer.pl net/can/bcm.c
Oliver Hartkopp [off-list ref] (maintainer:CAN NETWORK LAYER)
Marc Kleine-Budde [off-list ref] (maintainer:CAN NETWORK LAYER)
linux-can@vger.kernel.org (open list:CAN NETWORK LAYER)
linux-kernel@vger.kernel.org (open list)

At least posting via b4 relay works fine and downloading of the v2 
patchset you sent was comparably easy too.

Best regards,
Oliver
