Good.

Which wasn't necessary (yet) because creating the list did everything
that genaliases did.

Is lists.naturalintelligence.us in mydestination or is it a virtual domain?

If the latter, you need to put

POSTFIX_VIRTUAL_DOMAINS = ['lists.naturalintelligence.us']

in mm_cfg.py and run genaliases again and add

virtual_alias_maps = hash:/var/lib/mailman/data/virtual-mailman

to Postfix.

The Dovecot LDA does not understand the aliases. You may have
lists.naturalintelligence.us defined as a virtual domain for Dovecot.
This won't work.

This is really a Postfix issue, but we will try to help further if you
post the output from `postconf -n`.
