Hello,

I am getting a failed mailed delivery message every time I send an email.

The error reads:

host submission.antispam.mailspamprotection.com [34.111.121.216] SMTP error from remote mail server after end of data; 550 high probability of spam 1rITD-006zLY-2v

That is a general error message, so difficult to find a specific fix. All I can offer is to check your SMTP server settings to ensure it uses a password with security such as SSLTLS or STARTTLS.
