Hello,

I am working on changing the code of majordomo by hand to solve some 
major security problems with it.  The problems that I have are that 
1) anyone can post to the list by sending e-mail to list-l-outgoing 
and 2) anyone can get a copy of the list by sending majordomo telnet 
client 25, expn listname-outgoing even if I disable the who command 
in majordomo.  

Can anyone give suggestions on solving the above problems?

Someone suggested that I "have MajorDomo create a temporary copy of
the list each time a message is sent from the list".  How could I 
accomplish this?
