SMTP relay for cloud services RRS feed

  • Question

  • We have recently started using some cloud based hosting for our web services, and our developers have requested that we open up our Exchange SMTP relay services to the cloud so that they are able to send notifications from these hosted servers.

    I'm just curious as to what others have done in this situation ... Have you allowed the external servers to relay using your internal exchange enviornment? Have you used a 3rd party solution? Have you built another internal solution?

    Thanks in advance for any experience or feedback shared!

  • Hi,

    You can give a exchange user account to the developers. Then ask the developers to send the messages by authenticate with your exchange server. This will be more safe than opening relay for the servers.

    To allow the application servers relay off Exchange Server, please follow these steps:

    1. Open EMC, expand to Server Configuration->Hub Transport.

    2. In Receive Connectors tab, create a new receive connector.

    3.  In Network tab, under "Receive mail from remote servers that have these IP address", specify the the IP address of application servers.

    4. In Authentication tab,  select the option "Externally Secured".

    5. In Permission Groups, select the option "Anonymous users".

    Depends on your architecture, really. If you don't have an edge
    server, or 3rd-party front-end (e.g. a spam filter) then you don't
    have much choice but to trust your hoster.
