"There was a problem sending the test email."

i tried telnet, and got this:

root@lockquest:/var/discourse# telnet smtp.mailgun.org 587
Trying 52.35.57.220…
Connected to smtp.mailgun.org.

This is what the log said:

Like i said, the attempt to send to info@lockquest.com doesn’t appear on my Mailgun logs.

This is what my TXT records look like:

i haven’t uncommented/recommented that noreply@ line in the .yml from this troubleshooting guide yet:

https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326/2

The rabbithole.lockquest.com status on Mailgun is green and active. Yes, they have my credit card number.

" Are you using an IP address as the mail domain?" i don’t know. Where do i check that?
