Alarm pipeline failing to send email

I’m getting an error when trying to send an email via an alarm pipeline. The pipeline uses an SMTP profile, and when I test the profile I can send an email no worries. When I test the pipeline however to the same email (me), it fails with below:

Hello Nick,

Has this error already been solved? Because I have the same issue.
