smtp;551 This is not a relay host



    Here is my issue I have a partner in my firm who wants to forward incoming emails to an external address.


    So I did the old AD contact with the alternate address,  went to his user acct and in exchange general, delivery ops pointed to the contact.


    I tested this on my acct If i get email from people within my domain, it works fine a copy of the email gets to my gmail acct.  But if i get mail from an external email address this is the error the person who send me the email gets.

    Diagnostic-Code: smtp;551 This is not a relay host - mail must be to or from host domain.

    If someone can point me in the right direction would be much appreciated.

  • so your trying to relay mail through the exchange server which is authoratitive for neither the sender nor the recipient domain?

    Well I would'nt really say relay, Im just trying to forward a copy of all incoming emails to another address.

    But in answer to your question i guess it would be yes.


    Keep in mind that if I recieve an email from someone internal this whole thing works fine.

    I get an email a copy is sent to my gmail.  But if the origin is someone outside my domain then the error occurs.
