Dear all,
detail of the setup are-
::setup::
the setup consists of a dual processor red hat 7.1 Linux box running
majordomo version 1.94.5

The list (mylist) is used to distribute info to it's members. Only admin is
allowed to post .

following are some of the paramaters configured.
get_access          =   list
index_access        =   open
info_access         =   open
intro_access        =   list
moderate            =   no
moderator           =
mungedomain         =   no
restrict_post       =   mylist.restrict
sender              =   owner-mylist
subscribe_policy    =   closed+confirm

Now we gave the email address (support@mydomain.com) in the mylist.restrict
file. Other posts by members are bounced to the mylist-owner.

my majordomo.aliases settings:
mylist:    "|/usr/local/majordomo-1.94.5/wrapper resend -l mylist
mylist-list"
mylist-list:  :include:/usr/local/majordomo-1.94.5/lists/mylist
owner-mylist:   root,
mylist-owner:   root
mylist-approval: harshul@ealcatraz.com
mylist-request:  "|/usr/local/majordomo-1.94.5/wrapper majordomo -l mylist"

::problem::
1)anyone who can spoof the email address to (support@mydomain.com) can post
messages to the list. we need to restrict it. Some recepient mail servers
who bounce back the message do format the mail with the original header
values.

2)is it possible to restrict the posting from a single ipaddress, (that's
our ip address)

thanks in advance.
