-------------------------------
The Watchdog is trying to use the SMTP port 25 (xxx.xxx.xxx.xxx:25).
We can see that the SMTP port is set in DB to the correct port (587):

C:\Users\Administrator>telnet mail.xxxxx.corp 25
Connecting To mail.xxxxx.corp...Could not open connection to the host, on port 25: Connect failed
How to change the Watchdog Smtp.Port from 25 to 587?
Environment
Release : 21.2.8
Component : NETWORK FLOW ANALYSIS, DX NetOps Portal
Cause
In versions of NFA older than 21.2.8, the Watchdog ignored the SMTP port specified in the database and always used port 25.
Resolution
A fix for this issue is included in NFA 21.2.8 and up. In 21.2.8, you can specify the snmp port with:
mysql
use reporter
update general set value="25" where Attribute='Smtp.Port';
(specify the new SMTP port in place of 25)
