Multi-Tech Systems, Inc. FF240-IP Admin User Guide 94
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.
