TMS supports SMTP relay to send information concerning TMS related events. Specifically:
"Mail server access: Cisco TMS requires access to an SMTP server to be able to send email. Your company's existing mail servers can be used for this. Note that Cisco TMS supports SMTP Auth login for authentication if required."
