Other common problems occur within mail servers. Local email clients use the Post Office Protocol version 3
(POP3), an application-layer Internet standard protocol, to retrieve email from a remote server over a TCP/IP
connection. If the 920i’s IP address isn’t allowed to relay (send) mail, the message could be rejected. The email
server needs to be manually configured to allow the 920i to do this.

Additionally, the receiving mail server might get an email from the 920i and go back to ask the network’s mail
server if it, in fact, sent the message, which would make it allowable. Since the 920i sent the message, the mail
server replies with “No, it’s not from me” and the email is discarded. Again, a typical IT department is fully
capable of correcting this.
There may also be multiple spam filters existing within the network, any one of which could interpret the
message as coming from a fictitious address. The address from which the 920i sends an email must be added to
the server and added to any third-party spam filters as being a “safe sender.” The address will follow the format
[email protected], where “1” could be any number, depending on how many 920s are installed.
Of course, before the 920i can begin to function on a network, it needs to be assigned an IP address and be
configured. If this has not been done, refer to Section 3.0.
5.2.1
Troubleshooting Rice Lake Equipment on a Network
Due to a high number of variables, problems typically lie within the company’s network. To double-check that all
RLWS equipment is set up correctly and functioning properly, you can use Rice Lake’s free SMTP Test Server
program. This simulates a mail (SMTP) server, isolating the iQube and 920i from the network and making it easy
to determine where the problem lies. For example, if you have not been able to receive an email from the 920i but
the program shows it is functioning properly, you know there is an issue elsewhere on the network.
When an error occurs, the 920i makes one attempt to contact the mail server. There is a 15 second
timeout when unsuccessful. Before further troubleshooting, you should ensure the Ethernet card has
blinking lights. If the lights are blinking, proceed with troubleshooting. If they are not, there is a problem
with the card and/or cable.
Common Problems
•
Incorrect wiring the card
•
Port settings
•
Using crossover cable rather than patch cable (e.g., if you are connecting a computer directly to the card,
use crossover cable between the card and the computer--and you must use a static IP address; if you are
using a computer connected to a local area network, use a patch cable)
•
Server address (must be set last)
