Configuring and Using Email Notification
Configuring SMTP and DNS Settings
Requirements for
using SMTP To use the Simple Mail Transfer Protocol (SMTP) to send email when an
event occurs, you must define the following settings:
• The IP address of the Domain Name Service (DNS) server.
• The DNS name of the SMTP server and the From Address
settings for SMTP.
• The email addresses for a maximum of four recipients.
Note: To page an email recipient who uses a text-based pager
gateway, see the description of the
To Address setting
in Settings on page 21 .
DNS server To enable the Environmental Monitoring Unit to send email messages,
you must use the
TCP/IP & DNS option (Web interface) or DNS option
(Control Console) in the Network menu to identify the Domain Name
Service (DNS) server by its IP address.
If the unit does not receive a response from the DNS server within five
seconds, email cannot be sent. Therefore, use a DNS server on the
same segment as the unit or on a nearby segment (but not across a
WAN).
After you define the DNS server’s IP address, verify that DNS is working
correctly by entering the DNS name of a computer on your network to
obtain the IP address for that DNS name.
SMTP settings The Email option in the Network menu accesses the following SMTP
settings:
Setting Setting Setting Setting Description Description Description Description

account on the server for this setting.
