Having an issue with logging in on alternate browsers due to email isn’t verified. Would it be okay to export the database, manually make the change and then re-import it? Or could I connect to the database from a program on my computer to make the changes?
No idea. I’ve been playing with it all night but so far I haven’t managed to get the postfix-relay docker container to connect and send an email.
Have you configured OpenDKIM correctly? This tutorial might give you an idea or two. Gmail won’t relay mail unless its signed by your domain.
