Email sending not functional: 'Expected response code "250" but got code "501"' #4700
Description
Current Behavior
Sending email / a test email fails with the following error message:
Whoops!
An error occurred while attempting to test mail settings: Expected response code "250" but got code "501", with message "501 HELO requires domain/address - see RFC-2821 4.1.1.1".
This is despite setting the SERVER_NAME env var as per #3110
This was also not fixed by forcing the docker container's hostname to a hostname with --hostname myhost.domain.com or fudging with #3216 adding the line as per.
