OK, so I suppose it's a matching problem because the matching
logic is shared between IMAP and Maildir.

Any chance that List-Id doesn't match the older messages?

You are allowed multiple `watchheader' directives for an inbox
to account for address/name changes and such (and older headers
such as `X-BeenThere')

I haven't tried it, but this should work as long as you want
every message in a watched Maildir (or IMAP folder):

	watchheader = From:.

...which matches all messages with a literal `.' in the From: header;
so practically every valid message.  Likewise for Received:, Date:
or any practically-always-present header:value-substring combo.

I think everything else in your configs+commands looked fine;
but I'm still struggling with lack-of-sleep and could've missed
things :<


I designed the `watchheader' directives to handle multiple lists
funneled into one Maildir; but I suppose it's less intuitive for
users with a 1:1 list => Maildir mapping :x
