[Mailman-Users] Majordomo Interface?

[Ansel Freniere]

I am not a member of this list, so flames and other replies should go to 
this return address.

I would like to move our lists to Mailman from Majordomo, but Management 
wants any new system to be backward compatible with the Majordomo e-mail 
command interface.  Does mailman have this capability built in?  The only 
evidence I have found is on the Features page where it mentions 
"Majordomo-style email based commands."  Specifically, if someone signs up 
with majordomo commands, how is their password assigned?

The real question is: What are the issues with migration of existing lists 
from majordomo to mailman?

TIA.
