Hi; I've been using postfix for several years as a relay but never used it to restrict inbound mail, since it is done by an anti-spam appliance.
But now, we need to implement an inbound rule like this: 1. Everybody on our domain should be allowed to receive email form a specific sender (a...@xyz.com) - i.e. notifications 2. A few users should be allowed to receive email from any sender or domain. It seems to me that it is possible to achieve with smtpd restrictions, but I cannot figure out how to assemble senders and recipients parameters in main.cf. Any help would be appreciated. Thanks for your time. -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
