How are the email notifications sent?

ADDITIONAL INFORMATION:

I need to define routes so that email notifications can be sent. Does the RF650 do a MX lookup? If so what is the DNS server IP address? Does the RF650 then send mail directly to the destination server or does it relay through a Multitech SMTP server. If so, what is the IP address of the SMTP relay?

RESPONSE:

The RF650VPN sends email notification directly to the destination mail server, it does not do any relay.
