                requires the configuration to have "bboards: pop".

          The APOP and MPOP non-standard POP facilities are documented
          in _T_h_e _I_n_t_e_r_n_e_t _M_e_s_s_a_g_e (ISBN 0-13-092941-7), a book by
          Marshall T. Rose.  For more details, see support/pop/pop-
          more.txt and the _A_d_m_i_n_i_s_t_r_a_t_o_r'_s _G_u_i_d_e.  The APOP option
          peacefully co-exists with the standard POP, KPOP completely
          replaces the standard POP, and MPOP requires "bboards: pop".

          _F_i_l_e _L_o_c_k_i_n_g

          The file locking code has been cleaned up to support three
          kinds of kernel-level file locking.  As appropriate for your
          system, include the LOCKF, FCNTL or FLOCK option.  For more
          details, see _m_h-_t_a_i_l_o_r(5).

          Configuration Directives

          A number of new configuration directives have been added  or
          changed.  The full details are given in the READ-ME.

          cp:        The command used to  install  new  files  if  not
                     "cp".

          ln:        The command used to link files  together  in  the
                     source tree if not "ln".

          mts:       Full support for ZMAILER has been added.

          popdir:    The directory where _p_o_p_d will be installed if not
                     /usr/etc.

          regtest:   Set to "on" to prevent the hostname  and  compile
                     date from being included in _M_H binaries.

          sharedlib: You may now specify "sun4" or "sys5"  (for  SVR4)
                     shared libraries.

          signal:    Specifies the base type of the function  returned
                     by  _s_i_g_n_a_l().   This  was previously defined with
                     "options TYPESIG".

          Several `-D' options to _c_c have been added or changed:

          APOP       Authenticated POP (see above).

          AUX        Support for A/UX systems.

          DBMPWD     The DBM option has been renamed DBMPWD.

          HESIOD     Support for the HESIOD name server.

          KPOP       KERBEROS POP (see above).

          LOCALE     Support for local characters sets; uses the _s_e_t_-
                     _l_o_c_a_l() function.

          MAILGROUP  Makes _i_n_c set-group-id.  You may need this option
                     if your /usr/spool/mail is not world-writeable.

          MIME       Multi-media mail.

          MPOP       Mobile POP (see above).

          MSGID      Enables _s_l_o_c_a_l to detect and surpress duplicate
                     messages.

          OSF1       Support for DEC OSF1 systems.  May be incomplete.

          RENAME     Include this option if your system has a _r_e_n_a_m_e()

          Changes for MH 6.8                                         8


                     system call.

          SVR4       Support for System 5 Release 4 or newer systems.

          TYPESIG    This option has been dropped.  See `signal'
                     above.

          UNISTD     Include this option if your system has the
                     include file <unistd.h>.

          VSPRINTF   Include this option if your system has the
                     _v_s_p_r_i_n_t_f() library routine; otherwise, __d_o_p_r_n_t()
                     will be used.

          YEARMOD    Forces the _m_h-_f_o_r_m_a_t `year' function to return
                     2-digit values.  Use this option during a brief
                     transition period if you have local _m_h-_f_o_r_m_a_t
                     files which need to be converted to support 4-
                     digit years.

          _F_U_N_C_T_I_O_N_A_L _C_H_A_N_G_E_S

          In addition to the configuration changes mentioned above, a
          number of functional changes have been made to the system.
          Many programs have new features added and a few new programs
          have are provided. Each command's manual page gives complete
          information about the its operation.  Here is a short sum-
          mary of the changes.

          _M_H _S_e_q_u_e_n_c_e_s

          A larger number of user-defined sequences are available.
          Previously, this number had been 10.  On 32-bit systems, 26
          user-defined sequences are available.

          _P_r_o_f_i_l_e _C_o_m_p_o_n_e_n_t_s

          _M_H programs will now complain if the .mh_profile does not
          end in a newline.  Also, one enhancement and one new profile
          component are provided:

          Aliasfile:  Multiple filenames may now be given.

          Inbox:      New; the default folder (for _i_n_c, etc.) if not
                      "inbox".

          Changes for MH 6.8                                         9



          _F_o_r_m_a_t _S_t_r_i_n_g_s

          A few minor bugs were fixed in format string handling, and a
          few  new features were added.  See _m_h-_f_o_r_m_a_t(5) for complete
          details.

          Addresses      An  attempt  is  made   to   decipher   X.400
                         RFC 987-style addresses.

          Comments       Comments may be added to _m_h-_f_o_r_m_a_t  files;  a
                         comment  begins with the 2-character sequence
                         "%;", and ends with an un-escaped newline.

          %(modulo n)    The `modulo' function escape has been added.

          %(year{date})  The date parser has been enhanced  to  under-
                         stand  more  illegal date formats; `year' now
                         returns a 4-digit number.

          _U_s_e_r _I_n_t_e_r_f_a_c_e _P_r_o_g_r_a_m_s

          A number of _M_H commands have minor changes:

          ali       The output with `-user -list' was changed to match
                    the output with `-nouser -list'.

          burst     Will no longer drop the last message of a digest.

          inc       Accepts the `-apop' switch for authenticated POP
                    (see above); will attempt to detect write errors
                    (e.g., no space left on device) when incorporating
                    mail; no longer replaces newline characters with
                    NULLs.

          folder    The `-noprint' option was broken and has been
                    dropped.

          forw      Supports `-mime' to use MIME-style multi-part mes-
                    sages.

          mhl       Will no longer put an extra space at the end of
                    the `%{text}' in a formatfield.

          mhn       New; manipulates multi-media (MIME) messages; a
                    detailed man page is provided.

          mhparam   New; reads the _M_H profile (and context) and writes
                    the values of the specified components on the
                    standard output; useful in programmatic con-
                    structs.

          msgchk    Supports `-apop' (see above).

          Changes for MH 6.8                                        10


          packmbox  New; packs an _M_H folder into a UUCP-style mailbox.

          popi      New; a client-side POP initiator; available only
                    if you built _M_H with the MPOP option (see above).

          refile    A bug where the `rmmproc' did not remove all
                    specified message files has been fixed.

          scan      The `-file' option is fully supported and will no
                    longer complain about empty folders.

          send      Supports `-mime' and `-split' to split large mes-
                    sages into multiple partial messages using MIME.

          _S_u_p_p_o_r_t _P_r_o_g_r_a_m_s

          fmtdump   Can now read a format file, or a format string
                    given on the command line.

          popauth   New; manages the APOP authorization database (see
                    above).

          sendmail  The _s_e_n_d_m_a_i_l replacement will be installed only if
                    your `mts' setting uses the `/smtp' option.

          slocal    A new man page for _s_l_o_c_a_l is available; the new
                    `mbox' action is available to write a file in
                    _p_a_c_k_f format; a bug where extra `>' characters
                    were written to MMDF-style maildrops has been
                    fixed; if compiled with the MSGID option, can
                    detect and suppress reception of duplicate mes-
                    sages.

          viamail   New; bundles a directory (like _s_h_a_r) and sends it
                    through multi-media mail.






















                               December 14, 1992





          Changes for MH 6.7.2                                      11


          _C_H_A_N_G_E_S _F_O_R _M_H _6._7._2

          The MH.6.7.2 patch release is a maintenance release.  This
          is the current released version of _M_H as of February 1,
          1992.

               This release now supports the NCR Tower running SYS5R4.
          The WP changes installed in MH.6.7.0 have been removed.

          _S_h_a_r_e_d _L_i_b_r_a_r_i_e_s

          Support for SYS 5 shared libraries is in progress.

               Support for Sun OS 4.0 shared libraries had been
          improved.  The _M_H library has been modified to move initial-
          ized data into a data definition file.  The shared library
          will now consist of a libmh.so and libmh.sa file.  The
          shared library version number will no longer track the _M_H
          patch release number, and its numbering begins with version
          `1.1' with this release.

          _R_e_p_l_a_c_e_m_e_n_t _S_e_n_d_M_a_i_l

          Since many standard system programs expect to post mail by
          invoking /usr/lib/sendmail, a minimal replacement _S_e_n_d_M_a_i_l
          is provided in this release.  This replacement is meant to
          be installed on (e.g., diskless) client workstations which
          post mail using SMTP, and do not run a message transport
          system.  It will call _p_o_s_t to post mail; be sure you have
          configured _M_H with the `/smtp' mts option.  This sendmail
          replacement is installed in your _M_H etc directory, and you
          should link /usr/lib/sendmail to it.

          _F_o_r_m_a_t _S_t_r_i_n_g_s

          A manual page for the _f_m_t_d_u_m_p format string disassembler  is
          supplied, and some new format functions were added:

          folder   In _s_c_a_n, this component escape contains the name of
                   the current folder.  It is not defined for other _M_H
                   commands.

          getenv   This function escape returns the value  of  an  en-
                   vironment variable.

               There will be some additional changes in these routines
          in the next patch release.
