I opted in favour of -mda over -watch because Maildir performance
usually degrades linearly with the number of messages. A month of LKML
mail is anywhere from 25,000 to 40,000 messages, and maildirs tend to
handle that poorly due to peformance overhead of listing tens of
thousands of files in a single folder.

Obviously, I can set up an archival job, but then I'd have to worry
about messages that weren't actually imported into the archive (because
they didn't pass spam tests, but are actually ham, for example). The
-mda script gives me this for free, with such messages being put into
the emergency folder for later review.

It works, but cloning details at the bottom of the page expose both
addresses:

public-inbox-init -V2 lkml lkml/ https://[not-live-yet].kernel.org/lkml \
		linux-kernel@[not-live-yet].kernel.org linux-kernel@vger.kernel.org
