restricted_post trouble!

[Dmitry Sidorov <sidr @ sidora . net>]

I've installed majordomo, created mailing list called mylist and
created mylist.post file with email addresses who can post messaget to
this list. Then I added string restricted_post = mylist.post to
mylist.config file. But messages from any email addresses (not from
mylist.post file only) been allowing to sent to mylist. What is a
trouble? Maybe I have to make some other changes in configuration
files?
