47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	20 MH is a conceptual email system design and its concrete implementation.
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	21 Notably, MH had started as a design proposal at RAND Corporation,
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	22 where the first implementation followed later.
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	23 In spirit, MH is similar to Unix, which
42 af8c46461924 Rework and new text about mmh's name in the Intro. markus schnalke <meillo@marmaro.de> parents: 39 diff changeset	24 influenced the world more in being a set of system design concepts
32 6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	25 than in being a specific software product.
47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	26 The ideas behind Unix are summarized in the \fIUnix philosophy\fP.

32 6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	31 In 1977 at RAND Corporation, Norman Shapiro and Stockton Gaines
6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	32 had proposed the design
6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	33 of a new mail handling system, called ``Mail Handler'' (MH),
6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	34 to superseed RAND's old monolithic ``Mail System'' (MS).

32 6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	36 prototype of MH.
6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	37 Before the prototype had been available, the concept was
47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	38 believed to be practically unusable.
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	39 But the prototype had proven successful and replaced MS thereafter.
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	40 In replacing MS, MH grew to an all-in-one mail system.

47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	42 In the early Eighties,
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	43 the University of California at Irvine (UCI) had started to use MH.
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	44 Marshall T. Rose and John L. Romine became the driving force then.
57 8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	45 They took over the development and pushed MH forward.
8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	46 RAND had put the code into the public domain by then.
8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	47 MH was developed at UCI at the time when the Internet appeared,
8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	48 when UCB implemented the TCP/IP stack, and when Allman wrote Sendmail.
47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	49 MH was extended as emailing became more featured.
32 6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	50 The development of MH was closely related to the development of email
6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	51 RFCs. In the advent of MIME, MH was the first implementation of this new

57 8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	54 In the Nineties, the Internet had become popular and in December 1996,
47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	55 Richard Coleman initiated the ``New Mail Handler'' (nmh) project.
57 8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	56 Nmh is a fork of MH 6.8.3 and bases strongly on the

32 6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	58 Colman intended to modernize MH and improve its portability and

6a9abf543297 Rework in the Introduction (about MH). markus schnalke <meillo@marmaro.de> parents: 28 diff changeset	60 This should be done openly within the Internet community.
47 eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	61 The development of MH at UCI stopped after the 6.8.4 release in
eae5e50381ce Rework in Preface and Intro. markus schnalke <meillo@marmaro.de> parents: 45 diff changeset	62 February 1996, soon after the development of nmh had started.
57 8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	63 Today, nmh has almost completely replaced the original MH.

57 8776101db595 Intro: Fixed the history. markus schnalke <meillo@marmaro.de> parents: 54 diff changeset	67 However, the development revived in December 2011
