I have installed postfix onto my Ubuntu 18.04 server and I am receiving messages from a php script on a front-end submission into a /Maildir directory that I can view in the terminal.
But I am unable to add my POP email to a gmail account. Is there something I am missing? “We were unable to locate the other domain. Please contact your other provider.”
