Hi Mark,

Thank you.

Yesterday someone from debian list replied me, he asked to do:

$ touch /var/lib/mailman3/data/postfix_{domains,lmtp}
$ chmod 660 /var/lib/mailman3/data/postfix_{domains,lmtp}
$ chown list:list /var/lib/mailman3/data/postfix_{domains,lmtp}
$ postmap /var/lib/mailman3/data/postfix_{domains,lmtp}

and then it works, I think your solution:
$ mailman aliases
should also work.

Please report these issues to Debian. Otherwise their
package/documentation won't get fixed.

That said, the above errors are because Postfix can't send mail and
there are no Mailman specific Postfix alias files. This is because you
haven't yet created a list.


mailman aliases

This should create the /var/lib/mailman3/data/postfix_domains.db and
/var/lib/mailman3/data/postfix_lmtp.db files.

Fixing this may fix the 500 error. If not, we need more info as to what
the issue is. There may be a more detailed error in the web server's
error log or in mailman's log. The latter might be in
/var/lib/mailman3/logs/ or probably somewhere in /var/log/mailman3/
depending on how Debian set this up.
