smtp_rejected

HTTP status: 502 · Code: smtp_rejected

The SMTP server refused the email; detail carries its reply.

Why it happens

The SMTP server accepted the connection but refused the email. Its reply is in the error’s detail.

How to fix

Read the server’s reply. Common causes: the From address isn’t verified with your provider, or the domain lacks SPF or DKIM records.

Catch it in your code

Every SDK throws one error type for a failed call. Match on its code, which is always smtp_rejected for this error, never on the message.

JavaScript and Next.js

import { ErrorCode, OrvanoError } from '@orvano/js'

try {
  // your Orvano call
} catch (error) {
  if (error instanceof OrvanoError && error.code === ErrorCode.smtpRejected) {
    // handle smtp_rejected
  } else {
    throw error
  }
}

Dart and Flutter

import 'package:orvano_flutter/orvano_flutter.dart'; // or orvano_dart on a server

try {
  // your Orvano call
} on OrvanoException catch (error) {
  if (error.code != ErrorCode.smtpRejected) rethrow;
  // handle smtp_rejected
}

.NET

using Orvano;

try
{
    // your Orvano call
}
catch (OrvanoException error) when (error.Code == ErrorCode.SmtpRejected)
{
    // handle smtp_rejected
}

The error also carries the HTTP status (502), a message, and a request ID. Quote the request ID when you report a problem: the server logs it with the failure. See Errors for how errors work in every SDK, or every error code.
