I keep trying to use this with mailgun but keep recieving this error,
Failed to send test email! – Please check your outgoing email settings and server config to see if selected ports are open. Error details: The following From address failed: firstname.lastname@example.org : Called Mail() without being connected
Does anyone know how to fix this. I checked, the email i am trying to use is the main email so i know it works with my whmcs. I think i am using the right port 587 and selected tls as mailgun requires.
