Thanks for this, Odhiambo. Unfortunately it doesn't address my situation.

^^^^ Note the problem isn't the "From:" address. That is being correctly
configured from mailman-web.py and settings.py via the variables below.
The problem is it's going "To:" root@localhost. I don't know why this is
happening - shouldn't it be going to redac...@gmail.com?
Also, based on settings below shouldn't this be From:
postor...@lists.domain.tld
not From: r...@lists.domain.tld?

In the default files via the venv installation, these were already set
properly:
EMAILNAME='lists.domain.tld' <-- I set this myself
These were default in settings.py and mailman-web.py:
DEFAULT_FROM_EMAIL = 'postorius@{}'.format(EMAILNAME)
SERVER_EMAIL = 'root@{}'.format(EMAILNAME)
I set them explicitly to postor...@lists.domain.tld and
r...@lists.domain.tld and restarted mailman and mailman web, and this did
not change the problem with the server error and mail log entries above.

That was already set to my email address, and I do correctly get site
emails, such as cron output.
Further guidance would be appreciated.
