If someone could help with SMTP email problems, I'd appreciate it.

I'm unclear what is issuing the error message:
"554 relay-loopback4.smtpserver.com"

Here's what my email.yml config looks like:

production:
delivery_method: :smtp
smtp_settings:
address: xxx.yyy.com
port: 25
domain: xyz.domain.com
authentication: :none

1. user_name:
2. password:

Here's my production.log entry for an email send:
