Secure E-mail issues

E-mail address cannot be retrieved

Make sure that the printer e-mail function is secured

For more information, see Securing access to the application.

Make sure that user e-mail addresses are retrieved correctly

  1. From the Embedded Web Server, access the configuration page for the authentication module application.

  2. Make sure that the location of e-mail addresses to retrieve is set correctly.

  3. Apply the changes.

Check the LDAP settings

For more information, see Secure E-mail LDAP issues.

Signing certificate cannot be retrieved

Check the user’s signing certificate

Make sure that the user has a signing certificate and that the authentication module for retrieving certificates is configured correctly.

Signing certificate is unavailable

If the application is not configured to require a digital signature, then send the e-mail without a digital signature or return to the home screen to cancel the e-mail.

If the application is configured to require a digital signature, then make sure that a signing certificate is available for each user.

Cannot retrieve certificates from the LDAP server

Try one or more of the following:

Check the address book setup

For more information, see Configuring the address book.

Make sure that the address book function is secured

For more information, see Securing access to the application.

Check the LDAP settings

For more information, see Secure E-mail LDAP issues.

Make sure that the printer is connected to the network

Make sure that the network cables are connected securely and that the network settings of the printer are configured correctly. For information on networking the printer, see the Networking Guide.

Cannot encrypt e-mail for one or more recipients

If the application is not configured to require e-mail encryption, then send unencrypted e-mail to all recipients. You can also return to the home screen to cancel the e-mail.

If the application is configured to require e-mail encryption, then send encrypted e-mail only to recipients who have encryption certificates. Recipients without encryption certificates cannot receive the e-mail.

Make sure that each recipient is in the global address book and has a valid encryption certificate.

Cannot connect to the e-mail server

See Configuring SMTP settings, or try one or more of the following:

Make sure that the printer is connected to a domain

  1. From the Embedded Web Server, click Settings or Configuration.

  2. Click Network/Ports > TCP/IP.

  3. From the TCP/IP section, make sure that the domain name is correct.

  4. Apply the changes.

Note: For more information, see Configuring TCP/IP settings.

Check the SMTP Server Authentication setting

  1. From the Embedded Web Server, click Settings or Configuration.

  2. Click E-mail/FTP Settings > SMTP Setup.

  3. From the SMTP Server Authentication menu, do one of the following:

    • If the SMTP server requires user credentials, then select Kerberos 5.

    • If Kerberos is not supported, then select No authentication required.

    • If the server requires authentication but does not support Kerberos, then add the printer IP address or host name to the server as a relay.

  4. Apply the changes.

If the SMTP server uses Kerberos, then provide the host name instead of the IP address

  1. From the Embedded Web Server, click Settings or Configuration.

  2. Click E-mail/FTP Settings > SMTP Setup.

  3. From the SMTP Setup section, check the following settings:

    • Primary SMTP Gateway—Type the host name (not the IP address) of the primary SMTP server for sending e-mail.

    • Secondary SMTP Gateway—If you are using a secondary or backup SMTP server, then type the server host name (not the IP address).

  4. Apply the changes.

Make sure that Port 25 is not blocked

Make sure that the server and firewall settings are configured to allow communication between the printer and the SMTP server on Port 25.

Make sure that the printer is connected to the network

Make sure that the network cables are connected securely and the network settings of the printer are configured correctly. For more information, see the Networking Guide.
