3 Type the Primary SMTP Gateway Port number of the destination server. The default value is port 25. 4 If using a secondary or backup SMTP server, enter the IP address/hostname and SMTP port for that server. 5 For SMTP Timeout, type the number of seconds (5-30) the device will wait for a response from the SMTP server before timing out. The default is 30 seconds. 6 To receive responses to messages sent from the printer (in case of failed or bounced messages), type the Reply Address . 7 From the Use SSL list, select Disabled, Negotiate, or Required to specify whether E-mail will be sent using an encrypted link. 8 If your SMTP server requires user credentials, select an authentication method from the SMTP Server Authentication list. The default is "No authentication required." 9 From the Device-Initiated E-mail list, select None for no authentication, or Use Device SMTP Credentials if authentication is required. 10 From the User-Initiated E-mail list, select None for no authentication, or Use Device SMTP Credentials, Use Session User ID and Password, Use Session E-mail address and Password, or Prompt user if authentication is required. 11 If the device must provide credentials in order to send E-mail, enter the information appropriate for your network under Device Credentials. Viewing or deleting the security audit log • To view or save a text file of the current syslog, click Export Log. • To delete the current syslog, click Delete Log. Configuring 802.1x authentication Though normally associated with wireless network connections, 802.1x authentication is also used on wired networks to create port-based connections. Note: If using digital certificates to establish a secure connection to the authentication server, you must configure them on the printer before changing 802.1x authentication settings. For more information on configuring digital certificates, see "Managing certificates" on page 21. 1 From the Embedded Web Server Home screen, browse to Settings ª Security ª 802.1x. 2 Under 802.1x Authentication: • Select the Active check box to enable 802.1x authentication. • Type the login name and password the printer will use to log in to the authentication server. • Select the Validate Server Certificate check box to require verification of the security certificate on the authenticating server. Note: Server certificate validation is integral to TLS (Transport Layer Security), PEAP (Protected Extensible Authentication Protocol), and TTLS (Tunneled Transport Security Layer). • Select the Enable Event Logging check box to log 802.1x authentication-related activity. • From the 802.1x Device Certificate list, choose the digital certificate you want to use. If only one certificate has been installed, default will be the only choice listed. 3 Under Allowable Authentication Mechanisms, choose which authentication protocols the printer will recognize by clicking the check box next to each applicable protocol.
