    Wasn't sure how to search for this:

    Email forward: all-users@domain.com
    forwards to: user1@doamin.com, user2@domain.com, user3@domain.com

    I want to block access to all-users@ for anyone who is not emailing from @domain.com or maybe blocking anyone where the email does not come through the domain.com server would be better.

    Any help would be great. I imagine this would be a postfix config?

    Debian Lenny, mydns, courier, ispc 3.0.5.1

    Asking this again since I never figured it out.
