With all the email security these days there must be a way to set these systems easily. I have changed the main.cf , conical files, the voicemail.conf, setup a do not email from this email asterisk @mydonain.com restarting the server (postfix) and still it sends an email with asterisk@ as the sender. This is nuts the number of things that we have to go through. Is there a definitive guide on how to do this?
