What Is Causing This Error?
The SMTP error 502 typically signals that certain email settings or commands, although recognized by the mail server, are currently disabled or not activated. Essentially, the server can identify the SMTP command but might not support it due to its configuration settings.
This leads the server to return the error to the mail client, indicating a command it doesn’t support or hasn’t been set up to execute.
