I've no idea. A quick scan through an old Patchwork archive mbox I have locally
suggests no but I can't speak for other lists. That said, part of the issue here
could simply be lack of awareness of the feature as much as anything else.
Perhaps we should try to make this feature more prominent in the docs?

Evolution does make it pretty easy [1], as does mutt [1]. We could add these
links to the docs also, if it would help? I'll admit I haven't used either
myself though since I'm happy enough with 'git-pw' for my day-to-day work.
