[MM3-users] Re: Difficulties setting up MM3 with Postfix MTA in Docker Environment: Invalid EHLO domain name & Authentification as lists.local

Hi,

I managed to setup mailman using the maxking/mailman-* docker containers, connected to a postfix/dovecot mailserver and a mysql database.

To me it seems like mailman is trying to authenticate as “lists.local” or “mail.local” or “localhost” to postfix (which of course isn’t working), then issues a EHLO/HELO to postfix which is not a FQDN.

Why should MM authenticate against postfix? According to the docs:

"Please note here that if you choose to create the admin user using the environment variables mentioned above (MAILMAN_ADMIN_USER & MAILMAN_ADMIN_EMAIL), no password is set for your admin account. To set a password, plese follow the "Forgot Password" link on the "Sign In" page."
