============================== WARNING ==============================
Sending mail with Gmail is a violation of their terms of service.
Sending with G Suite might work, but it is not recommended. For information see:
https://meta.discourse.org/t/dscourse-aws-ec2-g-suite-troubleshoting/62931?u=pfaffman

======================================== ERROR ========================================
Connection to port #{ENV["DISCOURSE_SMTP_PORT"]} failed.
====================================== SOLUTION =======================================
The most likely problem is that your server has outgoing SMTP traffic blocked.
If you are using a service like Mailgun or Sendgrid, try using port 2525.

message = <<~STR
======================================== ERROR ========================================
AUTHENTICATION FAILED
#{e}
====================================== SOLUTION =======================================
The most likely problem is that your SMTP username and/or Password is incorrect.
Check them and try again.
=======================================================================================
STR
elsif e.to_s.match(/Connection refused/)
message = <<~STR
======================================== ERROR ========================================
CONNECTION REFUSED
#{e}
====================================== SOLUTION =======================================
The most likely problem is that you have chosen the wrong port or a network problem is
blocking access from the Docker container.
Check the port and your networking configuration.
=======================================================================================
STR
elsif e.to_s.match(/service not known/)
message = <<~STR
======================================== ERROR ========================================
SMTP SERVER NOT FOUND
#{e}
====================================== SOLUTION =======================================
The most likely problem is that the host name of your SMTP server is incorrect.
Check it and try again.

======================================== ERROR ========================================
UNEXPECTED ERROR
#{e}
====================================== SOLUTION =======================================
This is not a common error. No recommended solution exists!
Please report the exact error message above to https://meta.discourse.org/
(And a solution, if you find one!)

Mail accepted by SMTP server.
If you do not receive the message, check your SPAM folder
or test again using a service like http://www.mail-tester.com/.
If the message is not delivered it is not a problem with Discourse.
Check the SMTP server logs to see why it failed to deliver the message.
