The mailing list for listmasters using Sympa

[Thoralf Schulze <address@concealed>]

Hi there,

after upgrading from Debian buster to bullseye (and hence sympa 6.2.60
to 6.2.70), we are getting these error messages:

===
 User mailer-daemon@mout.$domain has encountered an internal server error
( - MSG_ID: $msgid - LIST: $listname@$list_domain):

Impossible to forward a message to $listname function return_path :
undefined in this list


See the logs for more details.
===

for various (but not all) of our mailing lists. I'll attach the
sanitizied logs of an affected list.

So far, the only solutions we've come up with is to delete and re-create
these mailing lists, which is a rather huge nuisance. Diffing the
configs of the broken vs. the newly created mailinglists doesn't show
any significant differences.

To reliable reproduce the issue, I renamed an affected list,
unsubscribed all users and subscribed only me - which caused the list to
work again :/

Is there anything more we can do to resolve this issue? return_path
doesn't seem to be a configurable option.

Thank you very much & with kind regards,
Thoralf.
