[Mailman-Users] From Address and non-member posts

[Yogesh Subhash Talekar]

hi

two questions:

1. When I post to my mailming list the From address comes like
"mylist-bounces at mydomain.com". Why can't I have the from address as the
address of the sender?

2. I want the posts from non-members to go through successfully and
without moderation? How to do it from command line?

Also, I want to make sure that non-members do not become memebers when
they post mails !

Thanks in advance.
