I'm sorry that I still have one more thing to ask. Even if the mail(sent 
to mailman@ via
that alias) is because of senddigests,  what exaclty does it mean?  I 
mean that what does
'post' commnad do(what is gonna happen if the 'post mailman' executed)?

As for the above,  do you mean that the admin is mailman user which 
specified as
a 'owner'  option?

On the other hand, I have joined mailman-users at python.org as you led me 
know.
