[MM3-users] Re: can't get mail into mailman3 in docker

so I added "- MTA=postfix" to the yaml file

services: mailman-core: . environment: - MTA=postfix ..

docker loks do not shoe a postscript error now

Postgres is up - continuing Using Postfix configuration Found configuration file at /opt/mailman/mailman-extra.cfg

BUT I still get this on the hosts mail log

[127.0.0.1]:8024, delay=0.16, delays=0.08/0.04/0.04/0, dsn=4.4.2, status=deferred (lost connection with 127.0.0.1[127.0.0.1] while receiving the initial server greeting)

I thought that setting would fixed it (thanks Matthew) but apparently not

Not sure what do do next? should I blow it all away and re install? What is that procedure?
