I've two questions. How do I configure a Mailman list to do the following? (1) Only allow @company.com to subscribe a Mailman list

Add the following regexp to Privacy options... -> Subscription rules -> ban_list

^[^@]+@(?!company\.com$)

If you want to accept subdomain addresses such as user@xyz.company.com, make the regexp

^[^@]+@(?!(.*\.)?company\.com$)

(2) Only allow certain email addresses to post

1. Set Membership Management... -> Membership Listdefault_member_moderation to Yes.

2. Set everyone's moderate bit On at Membership Management... -> Membership List - Additional Member Tasks.

You can leave the list like that and set a moderator password and tell the approved posters to post by including a header

Approved: moderator_password

in their posts. This is the "spoof proof" method - only people who know this password can post without moderation.

If you don't want to do that, you can uncheck the "mod" box in Membership Management... -> Membership List for those list members who are allowed to post, and if any non-members are allowed to post, add their addresses to Privacy options... -> Sender filters -> accept_these_nonmembers.

See the FAQ at <http://wiki.list.org/x/3YA9> for more.
