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.
Resolving the Error – Solution
When encountering the SMTP error 502, your first step should be to review your email configurations. Check if any SMTP commands are being disallowed based on your current settings.
If the configurations seem in order, it may be necessary to modify settings within your email host. For the best outcome, reach out to your email hosting provider’s support for guidance.
