I'm not an admin, but the answer is "highly unlikely".  To post to 
the mailing list, you have to be subscribed - because open mailing 
lists are subject to lots of spam messages.  And the only working 
way to enforce this is to check envelope from addresses at SMTP 
level.  In the past, we've tried to use qrantine with manual 
review of messages from non-subscribed addresses instead, but this 
simply does not work.

Consider using switching to a mail relay which does not try to 
change your envelope from address.
