 * I am trying to configure postman to send email through a remote server with a
   custom domain. I have added an SPF record to the DNS, gone through the wizard,
   and checked and rechecked the login info for the correct username and password
   and it all checks out.
 * The connectivity test shows that all ports are open, and 587 supports login and
   plain authentication. I have tried both with the same result. I have also tried
   the other ports to no avail as well.
 * If you have any other ideas besides the obvious ‘you have the wrong password’(
   I can use the same email and password to log in to the email account so I’m sure
   it’s not wrong), I would greatly appreciate the help.
