The effect of the template files not being readable by user "mailman" was interesting. Hundreds of lines like the following got written to mailman-core's var/log/smtp.log file at the rate of 4 per second:

That's a debug level log message written for every delivery. It has
nothing to do with the unreadable templates except that the unreadable
template causes looping in an attempt to send the message.
Did you perhaps set
[logging.smtp] level: debug
in an effort to diagnose the template issue?
Having excessively restrictive permissions on the template files is a silly - but easy enough - mistake to make. If it were possible to add it to Mailman 3, a more descriptive logging message could point others who make it in the right direction, perhaps. I spent a long time trying to figure out why messages weren't getting sent out from Mailman core, and in the end it was luck in form of a colleague's suggestion about file permissions that got me out of the rut.
There is clearly a bug in that an unreadable template should just be skipped and the fact logged. I have reported <https://gitlab.com/mailman/mailman/-/issues/745>.
