Hi,
I frequently get this warning mail.log. stat'ing the files give:

I don't understand how this is happening. With defaults for mailman.cfg settings you should have in the [mta] section
configuration: python:mailman.config.postfix
which points to the file mailman/config.postfix.py in the installation which has in its [postfix] section
postmap_command: /usr/sbin/postmap
These settings say whenever mailman updates
/opt/mailman/var/data/postfix_domains, it runs /usr/sbin/postmap
/opt/mailman/var/data/postfix_domainsto update/opt/mailman/var/data/postfix_domains.db. These files, postfix_domainsandpostfix_lmtp`should be written and closed before
invoking the posymap command, so Y don't understand why the
modify/change times on the .db files would be 1.22 seconds earlier than
those on the source.
I do not have the feeling that this is really a problem, cause everything works well. But it is confusing and misleading and might makes me missing a problem in the future, when the database is really outdated.
Could this be easily fixed in mailman?
I don't think it's a Mailman issue. For example on the server that supports this list I see

Which is what I expect.
Note that the only times both the postfix_domains and postfix_lmtp
are updated together is when one of the mailman subcommands aliases
or start is run. Are you possibly running both these at the same time
causing some kind of race condition?
