Mailmanit doesn't seem to be changing the settings of user options by email commands as it should.
Subscribing is excellent, so I *know* it is receiving the commands by email correctly, and I am CC'ing the emails to myself so that I *know* they are going to Mailman in the correct format, and I *know* they are going to the right address!
However, an email which has a subject line of:-
set authenticate XXXX address=yyyy(a)zzzz.com set delivery off
...*should* turn the delivery of list emails *off* for the member who is subscribed at yyyy(a)zzzz.com with a password of "XXXX"
But it isn't doing it.
I even receive an email back saying "done", but the membership roster does not show that delivery is turned off for that member.
I have also tested set ack on and set digest plain and so on. Nothing is working except my subscription requests.
Any ideas please? For me, Mailman is a server-wide installation shared by all lists on the server. It's not mine alone.
