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

[AIO]

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.

[bug-11887]Alarm Pipeline Fails to send (SMTP Profile working)

Paul, I managed to find a solution in this instance. In order to have the alarm notification work: SMTP profile must be configured with a hostname, but no username or password. [SMTP%20Profile1] Alarm Pipeline Notification Block must have the username in the from address. [Alarm%20Pipeline%20Config1] Following this set-up, it will allow the server to send emails via the notification pipeline without a password.
