Message Handling System
Message Handling System (MHS) is an important early email protocol developed by Novell.
Originally developed by Action Technologies, Inc. (ATI) in 1986, it was first licensed in 1998 then later bought outright by Novell.
Role as a gateway
MHS was a very 'open' system, and this, with Novell's encouragement, made it popular in the early 1990s as a 'glue' between not only the proprietary email systems of the day such as PROFS, SNADS, MCI, 3+Mail, cc:Mail, Para-Mail and Microsoft Mail[1][2], but also the competing standards-based SMTP and X.400. By 1996 it very clear that SMTP across the Internet would take over this role.
Work-alike products
A compatible range of gateway products called Connect2 from Infinite Technologies (now Captaris)[3] was also very widely used as part of MHS-based email networks.
Email clients
- Para-Mail. Paradox Development introduced version 2.0 along with Novell at Comdex 1986.
- DaVinci Email was the first Microsoft Windows-based email client, and used MHS natively.
- Pegasus Mail, a free mail client used MHS its native protocol[1].
- FirstMail, a cut-down version of Pegasus Mail bundled with some versions of Netware.
Decline
Novell became increasingly less supportive after their 1994 purchase of WordPerfect as they worked to transform WordPerfect Office into GroupWise.
At about the same time, confidence in the future of x.400 collapsed and SMTP email across the public internet became the compelling choice for mail between unrelated organisations, replacing MHS's former "glue" role.
