== 2.5. How do I set member options via email? ==

In just the same way as you can subscribe and unsubscribe from a mailman list by sending (for example) an email to: <mailinglistname-request@example.com> with the subject line: unsubscribe <password> address=member@example.com, I was under the impression that you can suspend delivery of list emails by sending an email to the same address with subject line: set delivery off <password> address=member@example.com

Is that not correct? If it IS correct, then why is it not working?

Setting member options via e-mail requires that the user be authenticated by a separate command prior to the set commands. E.g the above is done by

{{{
 set authenticate <password> [address=<address>]
 set delivery off
}}}

Since it is more than one command, at most, the first command can be in the message subject, the rest need to be in the message body.

The command

{{{
 set help
}}}

which doesn't require authentication can be used to get the list of set commands and their syntax.
