2.5.8.5 Protocol-Specific Details

Using remote operations (ROPs)

Sending a message to a remote recipient by using ROPs

Figure 24: Sending a message to a remote recipient by using ROPs

Note The ROPs are sent via RPC or MAPI extensions for HTTP. Several ROPs can be batched into a single request, as described in [MS-OXCROPS].

  1. The messaging client submits a message for delivery by using a RopSubmitMessage ROP request ([MS-OXCROPS] section 2.2.7.1), per the use case described in section 2.5.7, except that the recipient in this case is stored on a different server than the sender.

  2. The server determines that the recipient is not stored on the current server and locates the next hop for message delivery.

  3. The server invokes content conversion to convert the message into Internet-transmittable form.

  4. The server connects to the destination server and transmits the message via SMTP. For information regarding SMTP mail submission and Exchange-specific SMTP extensions, see [RFC2821] and [MS-OXSMTP].
