MHS: What the Gateway to MHS Does

The information in this article applies to:

• Microsoft Mail Gateway to MHS, version 3.0

The Microsoft Mail Gateway to MHS will poll a Microsoft "mailbag" for mail messages destined for transfer via MHS and create an MHS header from this when using MHS version 1.5N. The file is then placed in the MHS\MAIL\GATES\<Gateway-name>\IN directory, where the Connectivity Manager will pick it up for routing.

For MHS mail destined for Microsoft Mail, the gateway polls the MHS\MAIL\GATES\<gateway-name>\OUT subdirectory and transfers the message to the appropriate Microsoft Mail user.

There are differences between MHS version 1.5N and MHS version 1.1N in that version 1.1N requires messages to be submitted to MHS with a 128- byte binary routing envelope and a complete message header. This type of message format is known as SMF-64. MHS version 1.5N introduced support for SMF-70, which supports a much simpler format: no binary routing envelope is required, just a minimal submission header. MHS 1.5 will convert this header to a canonical header. The MS Mail gateway submits this canonical header type message when sending mail out.
