Problem Description:

    Bug 1038208 where a message with a "&" in the originator
    address causes the gateway to crash.  There are actually two
    changes:  one to quote the addresses passed to sendmail and the
    other to handle errors from sendmail better.

    Bug 1045390 where a message with a line of just a period
    cause premature termination of the message.  Now sendmail is
    called with the "-oi" flag to avoid this.

    Bug 1044955 where queue names starting with nn greater than
    29 would cause a configuration error.  Now queue names can start
    with any characters in [01][0-9:;A-Za-z], for a total of 128
    neighbor MTAs.

    Bug 1033761 where if there where the message "yacc
    stack overflow" would occur if the local.pns or local.unames file
    got modestly large.  There are other improvements so now the system
    can handle large files (tested up to 35,000 users).  Note:  on large
    files, the configure(8) program can take a *long* time -- this time
    can be reduced if the *.pns and *.unames files are sorted.
 
    MHS now correctly allows the use of sub-directory services:  several
    .uname and .pns files can be setup, one per organizational division.
    See the comments at "Local DS Configuration" in cfg/this.gc for more
    information.
 
    MHS allows for multiple domains in encoded_orname_pseudo_host.
 
    Bug 1030659 that caused free-form names to become
    corrupted on Sun 4's.
 
    Bug where a ")" in the subject line caused the MHS
    system to shutdown.
 
    Bug 1040226 where if the number of
    special_address_translations exceeds 200, the errors would show up
    in configure.  The fix increases the number of such items to 5000.
 
    This patch also allows one to specify that supplementaryInformation
    is not to be included in ReportedRecipientInfo in delivery reports.
    Some implementations of X.400, such as ATLAS in France, cannot
    handle this particular item.
 
NOTE:
 
    The this patch includes Sun 3 and Sun 4 executables.  Sun 2s are not
    supported by this patch.
 
    In the typical configuration, the MHS software is installed on one
    or more machines.  These machines are neither NFS servers nor
    clients as far as the MHS software is concerned.  This is called the
    standalone configuration.  This patch must be applied to each
    standalone machine.  
 
    If the configuration is such that some machines act as NFS servers
    for the MHS software to other clients, do steps (1) and (5) on the
    servers and clients and do steps (2) - (4) on just the servers.
 

INSTALL:

To install this patch, follow the following procedure
as root:
 
    Stop the MHS system if it is running using "mhsc -shutdown"
    (see mhsc(8)).
 
    Optionally, save the old software.

    Install the patch:
 
 Where "sunX" is either "sun3" or "sun4"
        cp -r sunX/*  /usr/sunlink
	cd /usr/sunlink/mhs.patch
        install.mhs.patch
 
    The install script will ask you to confirm its actions by asking a
    series of questions.  Unless you have an exceptional configuration,
    you should select the default (provided in brackets ("[]")) by
    typing RETURN.  If you have a safe copy of the whole distribution,
    you can answer "no" to the "Do you want to keep old copies of these
    files?"  question.
 
(5) Reconfigure and start the gateway:
 
        su mail
        cd
        configure
        rungateway &
 
The new software should be up and running.
