Problem with resctrict_post

Hello everybody
I have some questions about config majordomo 1.94.5
1. How could I corrctly define restrict_post option ?
   If I used only name of the list file or absolute path to that file it
does'nt matter. 
   For example: My list name is test. I used "resctrict_post=test". Also I
used "resctric_post=/usr/local/majordomo/lists/test". But anybody could send
message to [email protected] regardless he's in the file test. Why ?
2. I'd like to set up my Majordomo for accepting only one email-address,
both for [email protected] and [email protected]. None can send email
messages to those address except one. What should I set up in the config
files?
Thanx a lot
