I’ve installed mail-receiver and it is working fine. But my sysadmins don’t like it because they want to run Postfix locally installed on the VM, not the one in mail-receiver.
Is there a way to configure Discourse to receive email with a locally installed Postfix?
You can configure it to pull from a mailbox or have your admins configure their postfix using the stuff in the mail receiver container. The code is all there.
