A missed detail of the HTTPS config migration,
/usr/lib/mailman/Mailman/Defaults.py explicitly sets this:
PUBLIC_ARCHIVE_URL = 'http://%(hostname)s/pipermail/%(listname)s/'
Override that setting to https:// so that the archive URL embedded
in E-mail headers will no longer unnecessarily rely on our Apache
redirect. Once merged and deployed, fix_url.py will need to be rerun
for all the lists on both servers in order for this update to take
effect.
