Configuring SMTP Server Settings

Language:

Select Device Settings → Network Services → SMTP Server.
Note - If any email messages fail to be sent successfully, the failure event and reason appear in the event log.

Enter the information, as needed.

SMTP Server Setting	Description
IP address/hostname	Type the IP address or host name of the mail server.
Port	Type the port number. Default is 25.
Sender Email Address	Type an email address for the sender.
Number of Sending Retries	Type the number of email retries. Default is 2 retries.
Time Between Sending Retries	Type the interval between email retries in minutes. Default is 2 minutes.
Server Requires Authentication	Select this check box if your SMTP server requires password authentication.
User Name, Password	Type a user name and password for authentication after selecting the above check box. The length of user name and password ranges between 4 and 64. Case sensitive. Spaces are not allowed for the user name, but allowed for the password.
Enable SMTP over TLS (StartTLS)	If your SMTP server supports the Transport Layer Security (TLS), select this option.

Select the CA Certificate settings.

CA Certificate Setting	Description
CA certificate	Verifies the validity of the TLS certificate that will be installed. For example, the HPDU verifies the certificate validity period against the system time.
Browse	Imports a certificate file. Click Show to view the certificate content. Click Remove to delete the installed certificate.
Allow expired and not yet valid certificates	Forces authentication to succeed regardless of the certificate validity period. If you clear this check box, the authentication fails whenever any certificate in the selected certificate chain is outdated or not valid yet.

To test the SMTP settings, type the recipient email address in the Recipient Email Addresses field, with a comma to separate multiple email addresses.
Click Send Test Email.
Verify that the recipient(s) receives the email.
Note - The TLS and HTTPS protocols support AES 128- and 256-bit ciphers. The exact cipher to use is negotiated between the HPDU and the client (such as a web browser), which is impacted by the cipher priority of the HPDU and the client cipher availability and settings.
If you force the HPDU to use a specific AES cipher, for information on configuring AES settings, refer to the client documentation. For example, you can enable a cipher and disable the other in Firefox using the about:config command.
Click Save.
