hi , i configured my discource with normal gmail mail details , it is not sending any mail , i think i have to change the port number , how i can do that .
You can re-run
discourse-setup to change the mail settings.
If you didn’t run
discourse-setup, then see discourse/INSTALL-cloud.md at master · discourse/discourse · GitHub.
Using gmail is a violation of their terms of service and is not supported. See discourse/INSTALL-email.md at master · discourse/discourse · GitHub.
