PM8000 Is Unable To Send Emails

Issue
The PM8000 will not send an email even when the Alert module is setup correctly and on the same network as the SMTP server.

Product Line
PM8000

Environment
Sending alert via SMTP

Cause
This is an issue with all PM8000 firmware versions including and prior to V001.003.001 interacting with some SMTP servers. The PM8000 is able to connect SMTP server; however, the request is rejected with the error, "HELO requires domain address." This can be seen in a Wireshark capture:

No.	Time	Source	Destination	Protocol	Length	Info
		<PM8000>	<SMTP server>	SMTP	60	HELO
		<SMTP server>	<PM8000>	SMTP	94	HELO requires domain address

Resolution
This is a known issue and has been corrected in the firmware version V001.004.001
