[Bug-14441]: Alarm emails were sent error with SMTP profile

Nathan,

I realize this is late, but perhaps it can help you or someone else.
I ran into this same issue, and found that when trying to send via an SMTP server with a username and no password, I had to:

  • Configure the SMTP server with the hostname, but no username
  • Put the username in the From Address of the notification block.

This allowed me to send via the alarm notification pipeline.
