10.6 TROUBLESHOOTING E-MAIL NOTIFICATION (SMTP)
When e-mail notification via SMTP is configured and enabled, the SNMP/Web adapter will notify the
selected recipients upon UPS alarm activation / deactivation. If problems are experienced with this
functionality, follow the flowchart below to identify the root-cause of the problem and implement
proper corrective actions.
Please note that proper configuration of the SNMP/Web adapter and the SMTP server set-up and
configuration are responsibility of the user. This section aims to give basic troubleshooting guidance.
For details on SMTP protocol refer to RFC 821, RFC 1123 and RFC 2821.

(*)If the adapter and the SMTP server belong to different subnets check the gateway settings.
(**) Particularly:
• If the SMTP server supports logging, enable the log functionality. Server error messages may
give useful hints on the nature of the problem
• Check the SNMP/Web adapter hostname (must be a valid domain name), SMTP sender-name
and e-mail recipient (both must be valid e-mail addresses)
• If the SMTP server requires authentication, verify the account settings on the SNMP/Web
adapter.
With reference to Authentication, the embedded e-mail client only supports the CRAM-MD5 and LOGIN
mechanisms. Make sure the e-mail server supports at least one of these mechanisms.
