Some of or Outlook or Gmail “Message blocked” email sending/receiving errors are self explanatory:
550 5.7.1 The person you are trying to reach is no longer at ACME inc.
550 5.4.1 Recipient address rejected: Access denied
554 5.7.1 [CS01] Message rejected due to local policy.
The first two basically mean that you have the wrong email address or it just doesn’t exist, and the third one means they have marked you as spam or you need to be added to their contacts or whitelisted by their email administrator.
But, on the other one in particular can be quite puzzling like:
550 5.7.26 This mail is unauthenticated
And this one can make you struggle with situations like:
- Unable to send email to Gmail address or Outlook address
- Gmail rejects my emails
- Outlook rejects my emails
- Gmail Message Blocked mail is unauthenticated
- Gmail rejects email from my domain / from me
- We have been trying to email customers with gmail addresses and the emails keep getting blocked
