4.4. SMTP configuration
The UPSLink can send an email notification when an UPS alarm has been detected and/or when
scheduled time for system log messages expires. The user must configure a valid SMTP server to
send these automatically generated emails. The UPSLink supports three SMTP server types:
•
SMTP without authentication
•
SMTP with authentication
•
POP-before-SMTP
These examples can be seen in
Figure 4-4
. Required parameters for each SMTP configuration
include:
•
SMTP server IP address
•
Device mail address
•
SMTP user name
•
SMTP user password
The device mail address specifies the sender’s email address for all log and alarm delivery emails.
SMTP servers often check only the sender’s host domain name of the email address for validity. .
Consequently, the email address set for the device can use an arbitrary username with a registered
hostname (i.e.
or
)
.
The SMTP user name and SMTP user password are required when either SMTP with authentication
or POP-before-SMTP mode is selected.
