All emails including password emails are blocked

Issue Summary

Customer wanted to limit email notifications to only password emails being sent, so they set Send only password emails to "Yes".
Unfortunately this blocked ALL email notifications with the Status = "error: 5"

In the backend Splunk log we could see that the "reason" was "Not a password email"

Steps to Reproduce

Send only password emails is set to "Yes"

Expected Results

Password emails would be sent.
All other email notifications would not be sent.

Actual Results
