[Mailman-Users] using hash for aliases. distribution email bounced back with errors

Sat Jun 15 10:01:14 EDT 2019

I made those changes and attempted another distr test and most of the
previous errors went away but one (still no distribution), as follows:

This is the mail system at host naturalintelligence.us.

I'm sorry to have to inform you that your message could not be delivered to
one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can delete your own
text from the attached returned message.

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`.
