SMTP and email notification in HPE OneView

The appliance automatically determines the SMTP server from the domain name in the appliance email address. Use the SMTP options available in the HPE OneView UI to specify the SMTP settings.

The appliance discovers the server host name and IP address details from the mx records of the DNS server. The standard SMTP port is 25. You can confirm if the mx records are configured on the DNS by running the command set q=mx followed by domain name on the nslookup utility. However, some DNS servers might use a round robin schedule so the retrieved list could change every time the query is run.

You can manually configure SMTP when:

• The mx records in the DNS server are missing

• The DNS is not reachable

• The SMTP server is using a nonstandard port

Provide a password if your SMTP server requires authentication. The appliance verifies the credentials using the SMTP LOGIN authentication mechanism.
