What error does the sender see with a rejected message?
The HiWAAY email gateway rejects messages with different errors depending upon the reason the message failed to pass through the HiWAAY sendmail filters. Where the senders address can be determined (highly unlikely if the message was spam), the sender will get an automatic return message, known as a ‘bounce’ notice from their gateway which will indicate their message failed to deliver to HiWAAY. In most cases the bounce notice tells the sender what to do to correct the reason the message was rejected. Depending upon the type of error, sometimes their gateway will keep trying to resend the message.
