That doesn’t say anything about why the delivery failed.
This one is only the beginning of a message, that may eventually be able to add value, that can be used in order to assist you.
However, the important parts (e.g. the stuff that come below “The mail system”) are missing in your message above.
It will typically say something like:
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system

Status: 5.1.1
Remote-MTA: dns; mx1.smtp.goog
Diagnostic-Code: smtp; 550-5.1.1 The email account that you tried to reach does

The example above would indicate that “[email protected]” tried to send a message to “[email protected]”, where the mail server named “mail.example.net” could not deliver it to Google, because Google refused the delivery with the “550 5.1.1” status code, as well as an elaborative error message, indicating that the email address [email protected] does not exist.
These two sections are MANDATORY, if anyone anyone should be able to assist, or otherwise be able to look further in to the problem with you.
