Thanks, I'd probably add "-name '*.pm'" to find(1) to filter out
directories.  But I wonder if it's better to grep the MANIFEST

Sure.  There's a bunch of places where we just die() and ignore
sysexits.h or similar.  Could use some help checking for that
and patches are welcome :>

Oops, I thought this was standard :x  Care to send a patch to
INSTALL for that?

If anything, I'd rather list ALL the recent participants in a
thread (it wouldn't require extra lookups).

But my philosophy is not to give anybody more credit/weight than
anybody else; and I'd rather people follow links if the Subject
seems interesting, not because who started a particular topic
(especially when it comes to emails with [PATCH] subjects).

I also prefer to avoid having too many options to reduce
support/documentation costs, so if we do something like this,
it would be the default.  But also, it's more clutter.

Not currently...  I'm not sure how the UI or configuration
should be or how to avoid clutter/scalability problems with many
inboxes.  NNTP has standardized commands and clients can decide
how to show them, at least.

mkdir /srv/public-inbox/{meta,test} # static directory listing

Rack::Builder routes meta/ and test/ to varnish => public-inbox-httpd

All the HTTPS, static files and reverse proxying is handled
using yet-another-horribly-named-server written in Ruby and Rack :)

I prefer to use public-inbox-watch for mirroring existing lists.

-mda is also a bit strict and opinionated (though I have plans to
make it less so, optionally), so it's mainly for non-mirrored

-watch is also safer and less likely to lose/bounce mail since
it hits a Maildir, first.  -watch will scan for List-Id (or any
other header, such as X-Mailing-List) and put it into the
correct inbox.  If space is a problem, a cronjob to remove
old files will help, but maybe it can unlink-on-import-commit
in the future.

I haven't thought much about mirroring with -mda, but I suppose
having a per-list subscriber address and extra
publicinbox.<name>.address entry works, too.
