It's fairly well hidden, and in fact this is some dinosaur-old code. 
For the Pythonically inclined, search Mailman/Utils.py for the
is_administrivia() function.  Above that is a dictionary of email
commands to 2-tuples of the form (min #args, max #args).  The tuple
specifies the minimum and maximum number of arguments to the command
that must be present for it to be recognized as a command.

The "who" command has a min and max of 0, so a bare "who" in the Subject
will definitely trip it.
