550 5.7.0 Relay Access Denied RRS feed

  • Question

  • Greetings all!

    I have setup my Office 365 email account for a new domain and am able to send and receive email at that domain.

    We are currently using our old domain name to send and receive email through MXLogic (server based virus/spam filter service) to our onsite Exchange 2003 server) MXLogic also provides a service call "Intelligent Routing". This allows brian@olddomain.com to be routed to brian@newdomain.com. However, when I try to route to our new domain at office 365 I get the following error:

     This message was created automatically by mail delivery software.

     A message that you have sent could not be delivered to one or more recipients.  This is a permanent error.  The following address failed:

       brian at olddomain dot com>: 550 5.7.0 Relay Access Denied

    I have several other domains (on Exchange servers not office 365) that are sucesfully routed  without any problem

    Any help would be greatly appreciated.

    Thanks,

    Brian

  • Hi,

    it's not exactly clear to me what the intetion is behind this domain routing. Can you explain it in more detail.

    Greetings
