The app sends emails to the registered users in dependence off a workflow-state. - the sender-email-address is an email-address of the affiliated business (marketing decision) - in some cases the affiliated business whants also to receive a CC of the message. But its email-server will not accept an email (sender-address) of its domain coming from outside of their network (SPAM-prevention). => Thats because I _must_ send the email in my address, but for marketing reasons all other emails must be send like they are send now (in their name)
The actual solution is, that I send all emails for j...@example.net to a third email-server which has a sender_canonical-rewrite rule. This emailserver sends the email than forward with the changed sender-email-address to the MX of j...@example.net. This runs so actually successful for years. But I'm confident that there must be also a solution to solve the problem using only one email-server. Is the problem understandable? Karfunckel
