MeterM@il Internal Email Server Feature Technical Note
The network components for using MeterM@il technology are described below. 
Ethernet network: Ethernet is the connection medium for the delivery of email 
from a meter to an SMTP server.
Workstation with ION software: A computer with ION software is required to 
set up a meter equipped with the MeterM@il feature. Refer to “Configuring the 
Meter for MeterM@il Technology” on page 242.
Meter: The meter can be connected to your LAN like any other network device.
SMTP mail server: The MeterM@il feature requires an SMTP mail server to be 
configured to forward email from the meter to the final destination of the email 
message. The SMTP server may be located on your Ethernet network or 
accessed via a dial-up modem connection. 
BootP server: A BootP server can be set up to automatically configure meter 
network settings. See “Automatically Configuring Meter Network Settings” on 
page 238
. (BootP is not available for ION 8000 Series meters.)
Firewall: If the SMTP server that the meter uses is beyond the corporate 
network, you must configure the firewall to allow outgoing connections on TCP/
IP port 25 from the meter to the SMTP server. If the SMTP server is within the 
network, no additional configuration is required.
SMTP Connection Timeout
For meter email transmission, an SMTP mail server which is configured to forward 
email from that meter to the final destination is required. The SMTP mail server 
may be located on your Ethernet network (as illustrated above), or accessed via a 
dial-up modem connection (as illustrated below). If the SMTP mail server is 
located on your Ethernet network, the connection between the meter and the 
SMTP server is usually made quickly. If the SMTP mail server is accessed via a 
dial-up modem the connection can take longer, and can cause the meter to 
terminate the attempted connection to the SMTP server because the server takes 
too long to respond. 
You can extend the SMTP Connection Timeout interval on your meter using the 
SMTP Connection Timeout setup register in the Ethernet Communications module:
If the SMTP server is on your local network, you can most likely leave the SMTP 
Connection Timeout
 setting to its default of 60 seconds.
If the SMTP server is accessed via a dial-up connection, the SMTP Connection 
Timeout
 should be extended to allow for extra time to establish a connection. The 
exact time setting depends on the speed of your dial-up process.
The SMTP Connection Timeout register can be set through the meter’s front panel or 
with Designer software. See “‘Setting Up the Meter for the SMTP Server” on 
page 242.
