Comment 3 for bug 727602

Perhaps it is an error message bug. What response did you get?

Why do you think "who" on its own should be OK? This is only acceptable if the roster is public. If the roster is not public, password authentication as a member (if the roster is available to list members) or as a list admin or moderator is required.

If the command should be "who XXXXXX <email address hidden>" then putting that in the subject will work, and putting that in the body with no subject or at least a non-command subject will work, but putting that in the body with just "who" in the subject should give a usage message in response to the "who" in the subject and indicate that the "who XXXXXX <email address hidden>" in the body was unprocessed.
