I used Windows 10’s WSL2 to install Docker and deployed my own Discourse application.I modified the SMTP configuration items in discourse/config/discourse\_defaults.conf, and re-ran d/boot\_dev -p, d/rails s, and d/ember-cli, but the email still cannot be sent. I have no way of determining where the problem lies.Should I configure SMTP in discourse/config/discourse\_defaults.conf? I used d/mailhog to test, but the bash just kept repeating “[APIv1] KEEPALIVE api/v1/events”.Is there a convenient and obvious way to verify the validity of my SMTP configuration?
