After installing Artica Mail, you must learn to your server which networks will be able to send message to Internet.
- Under “Messaging” section, under Infrastructure area, choose “Postfix Network settings“
- Add in the “What Clients to relay mail from ?” list a new Address or an IP range.
Each network added in this section explains to the relay that messages are sent in outgoing mode and should be not scanned for Anti-spam feature.
