[MM3-users] Re: Mailman REST API not available. Please start Mailman core.

[Does your systemd script set the user to the Mailman user, and does the Mailman user have read/write permission on Mailman's var/locks/?]

How do I check for that?

Also, what's the difference between the mailman command and the systemctl mailman3? Are they the same processes?

Oh and does the /3.1 matter at the end of the Rest url for Django?
