Abstract

MHS Routing is the problem of controlling the path of a message as it traverses one or more MTAs to reach its destination recipients. Routing starts with a recipient O/R Address, and parameters associated with the message to be routed. It is assumed that this is known a priori, or is derived at submission time as described in Section 23.
