OpenVMS …empowered



Message Exchange (MX) is a mail delivery system for OpenVMS originally developed by MadGoat Software. The company MadGoat Software has ceased to exist as of December 2006. In April 2008 the software was gathered up and released under a BSD-style license as MX V6.0 by Matt Madison (former owner of MadGoat Software).

Since then Kednos has decided to take up hosting the software (although there are several other sites that have also picked up the source kit) and setup a support community, starting with the resurrection of MX-LIST.

The Future

At present MX V6.0 does not support VAX, X.25 or UUCP. There are plans to restore the VAX portions of the kit in the very near future. It may be possible to add support for X.25 and UUCP if there is interest.


The following MX kits are available for download:

The following utilities are also freeware packages released by MadGoat Software. MMK and NETLIB iare required to build MX from source.
