Wasn't sure how to search for this: Email forward: [email protected] forwards to: [email protected], [email protected], [email protected] 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
