Actually, any mail sent to the -subscribe or the -join address is a 
valid subscribe request and as long as subscribe_policy includes 
'confirm' will result in a subscription confirmation to the (forged) 
From: address.

Only mail to the -request or -confirm addresses produces 'unrecognized 
command' or 'invalid confirmation' responses.

This will be addressed in Mailman 2.2, but currently, only by modifying 
code in Mailman/Queue/CommandRunner.py and/or the various 
Mailman/Commands/cmd_*.py modules.
