Hi Harald, We have many agencies that can use our mail server. Each agency has one or more domain name. They can add their domain in our system to receive their emails professionals.
We have already limited the users who have the right to the domain name in the system, but there are always "failures"... The last example, a external agency computer has added the domain "paypal.fr" in our system and have creating an e-mail (catchall). He received all the messages that our employees have sent to paypal.fr ... We monitor the domaines added to the system. But we can not monitor employees who have the right to add domain names. I am looking for a solution in the Postfix configuration to force it to always send emails to the outside and not try to deliver them locally. Regards, Damien
