The following are the differences between nmh and MH-6.8.3.
UCI has released MH-6.8.4, but the new features it adds have
not yet been added to nmh.

GENERAL
-------
*) nmh has been converted to autoconf (configure) and should be
   more portable and generally easier to install than MH.
*) All of MH's Makefiles have been rewritten for nmh.  You can now
   use GNU make without any problems.
*) The source code for nmh has been cleaned up (somewhat).  It now
   requires an ANSI C compiler (gcc is fine) to compile.
*) A new option `-version' has been added to all the commands.
*) The POP server (popd) has been removed, although client-side
   support for POP is still present.  Also nmh doesn't currently
   support some of the alternate forms of POP such as APOP or KPOP
   that are contained in MH.
*) The support for bulletin boards is currently not supported and
   may be removed.
*) Currently nmh doesn't support using shared libraries for libmh.
   This may return in the future, but is not a high priority, since
   the nmh commands are not that large.
*) The mhook man page has been split into man pages for
   rcvtty, rcvdist, and rcvpack.

FLIST
-----
*) A new command `flist' has been added to nmh, that will list the
   folders that contain messages in given sequence (such as the unseen
   sequence)

SLOCAL
------
*) Added new action `folder' or `+' to slocal, which is shorthand
   for piping the message to rcvstore.
*) Added new options -[no]suppressdup to slocal to check for duplicate
   messages.  The code for suppression of duplicate messages (MH config
   was MSGID) is now always built into slocal.
*) Improved the debugging output for slocal.  It will now warn when an
   entry in the ".maildelivery" file is skipped because of not enough
   fields.
