As far as I'm aware it defaults to using:

So, anyway, with that minor tweak, does leave things a bit
simpler and (more "guaranteed") consistent.

I'd earlier put in per-list tweaks in:
(via the admin web GUI) when, after lists had been moved, but
archives not yet moved and merged - older archives were still on
DreamHost.com hosting - so had some custom information in there to
provide that information and additionally links to the older archives.
Since that's now all merged and moot, have done away with those
unneeded customizations regarding two separate archive locations
(current and older).

The other bits mentioned earlier regarding customizations around
blank body anti-spam rejects work-arounds (notably tweaking
instructions mailman gives to users, etc.) - those customizations
are located in other files - and those remain - at least until
I/we theoretically get around to fixing that particular false
positive on the anti-spam SMTP rejection.
