I have a shopify account which sends emails to and from my email address. Postfix is giving a 550 error because the from address hasn't been verified and it is refusing to relay it. The only destination is my own E-mail address.
I'd like to know what settings I need to change so that postfix installed via iredmail will allow these spoofed emails for local delivery only.
Dear sir, honestly i never worked before on the same but i can try to fix the issue as its my favorite domain of troubleshooting already done many resolution regarding to emails locally as well as on freelancer.
looking forward for your acknowledgment.
