Hi,

I think you should have a look at
http://docs.mailman3.org/en/latest/config-core.html#configuring-mta

Postfix is the default MTA when none is specified, thus the behaviour you
observe.

Change your configuration files and this should be gone. (think about
removing the empty file, as it's not needed)

Come back at us if this doesn't solve your issue.

It's far easier to fight for one's principles than to live up to them.
