SUMMARY
Version 3.0 of the Microsoft Mail Gateway to MHS supports MHS versions
1.5N, 1.5M, 1.5P, and all earlier versions, including versions 1.11
and 1.21.
N after the version number denotes that it is a NetWare version
M after the version number denotes that it is an MS-Net compatible
version (for example, LAN Manager).
P after the version number denotes that it is a personal (standalone)
version.
The gateway can operate as an SMF level 70 gateway when installed on
MHS version 1.5 hosts. It can optionally be run as an SMF level 64
gateway if the situation demands this.
On version 1.21 and 1.1 hosts, the gateway always operates as an SMF
level 64 gateway. This is a limitation in the MHS version, not in MS
Mail; MHS 1.21 and 1.1 do not support SMF 70.
