[Mailman-Users] list aliases - /etc/mail/aliases

[Noah]

mailman 2.01
OS:  FreeBSD4.8
Sendmail 8.12.9

can somebody point me to the documentation which discusses aliasing lists.  I
cant seem to find it. 

I am attempting to alias  'dream' to post to the 'dreamweavers' mail list.

this is what I places in the /etc/mail/aliases file:

dream:              "|/usr/local/mailman/mail/mailman post dreamweavers"

but posted mail to this list _from a list member_ gets held for moderator
approval.  mail to dreamweavers posts fine.

clues please?
