Appendix A: Troubleshooting

No email message after mail server setup (cont’d)

CAUSE E: The email server does not support SMTP.

RESPONSE E: Contact the FF240-IP unit using secure shell either at its IP address or name (if a name server is present) and specify the SMTP Port Number (25 is the common/standard port number, but this number is configurable in the FF240-IP System Configuration SMTP screen). Using Telnet (IP address: port) to get to the SMTP server is the easiest method.

The email server should then return a “Welcome” message.

Type EHLO

The email server should then return a listing of supported protocols and other information.

If the email server does not respond with a ‘Welcome’ message, or, if it does not respond to EHLO, then, either the email server does not support SMTP or the port number is wrong (that is, the port number used in the telnet command does not match what was already specified in the System Configuration SMTP screen).

If the email server does not support SMTP, it will not inter-operate with any FF240-IP unit.

CAUSE F: A discrepancy exists between settings established in the FF240-IP System Configuration SMTP screen and the email server’s requirements for User ID and/or Password in establishing authentication with the FF240-IP.

After you have set the FF240-IP Administrator’s email address, go to the System Configuration SMTP screen and click “Update.” In response to this, an email will be sent to the FF240-IP Administrator.

Email servers have different requirements about User ID and Password with respect to authentication to another server. In order to authenticate, some email servers will require a User ID and Password and will reject authentication if a User ID and a Password have not been provided. For other email servers, a User ID and Password are not required and not allowed and these email servers will reject authentication if a User ID and Password are included.

RESPONSE F: Consult with the administrator of your email server about its User ID/Password requirements for authentication. Then configure the FF240-IP’s System Configuration SMTP screen fields accordingly. The specific fields are “SMTP Server User ID” and “SMTP Password.” Leave these fields blank or fill in these fields according to the requirements of your email server.

3. SMTP Error Code List

Many messages now contain the last response from the email server. These error codes may be looked up to give more details of exactly what occurred. The Internet Engineering Task Force (IETF) maintains information about SMTP error codes. You can look them up online at ietf.org in the RFC repository.
