Forgot Password API

I’m attempting to make a request to this route: http://localhost:1337/api/auth/forgot-password following the documentation listed here, however, I get a 400 response with the following Application error:

1. "SMTP code:553 msg:553 5.7.2 [TSS09] All messages from will be permanently deferred; Retrying will NOT succeed. See\r\n"

I’ve attempted using this route as well: http://localhost:1337/auth/forgot-password, with similar results.

did you find a sollution ? i have the same error
