'The recipient server did not accept our requests...'
This error message means that we tried to reach the server of the person you’re sending an email to, but didn’t get a reply, so we couldn’t send your email. This could be a temporary problem, and we suggest you try again later.
You could also contact the customer service department of the other domain (the one you’re sending to). The problem might be because:
- The other domain doesn't have up-to-date MX records or is otherwise misconfigured.
- The other domain is blacklisting or graylisting messages from Gmail.
- The other domain has temporary networking problems.
