So I'm partway there...
I figured I could define an Archive context, and discovered
mu4e-view-auto-mark-as-read. I have an Archive context, and when in it
and when mu4e-view-auto-mark-as-read is nil, the right thing happens.
However, I can't get the Archive context to enable soon enough. I'm
guessing the :match function only runs when pressing a refile action,
not when loading a message. Is there a hook or some way I can get the
:match to run more often?
Thanks,
John
