Hey everyone, I’ve been wrestling with setting up SMTP on my Discourse installation, and it’s been quite the challenge. I’ve delved into numerous posts like this one without luck. Here’s the scoop: I suspect my issues are tied to the format and length of the username and password that I’m required…
