Name
       mtstailor - system customization for MH message system

Description
       The file defines run-time options for those MH programs which interact (in some form) with the message transport system.  At present, these
       (user) programs are: and

       The options available along with default values and a description of their meanings are listed below:

       The host name that MH considers local.
		 If not set, depending on the version of ULTRIX you are running, MH will query the system for this value (for example: <whoami.h>,
		 gethostname).	This has no equivalent in the MH configuration file.

       The name of the local host in the UUCP "domain".
		 If  not set, depending on the version of ULTRIX you are running, MH will query the system for this value.  This has no equivalent
		 in the MH configuration file.

       A host or list of hosts running
		 can be specified.  When an MH program is run, it uses this entry to search for a central to connect  to.   This  is  particularly
		 useful for workstation users who may not have running on their workstation.

       The directory where maildrops are kept.
		 If this is empty, the user's home directory is used.  This overrides the mail field in the MH configuration file.

       The name of the maildrop file in the directory where maildrops are kept.
		 If this is empty, the user's login name is used.  This overrides the mail field in the MH configuration file.

       The beginning-of-message delimiter for maildrops.

       The end-of-message delimiter for maildrops.

       If non-zero, then support for MMailids in
		 is enabled.  Basically, the field in the password file is of the form
		 My Full Name <mailid>
		 The MH internal routines that deal with user and full names will return mailid and My Full Name respectively.

       The locking discipline to perform.
		 A  value  of  0 means to use if available, standard locking otherwise.  A value of 1 means to use locking always (the name of the
		 lock is based on the file name).  A value of 2 means to use locking always (the name of the lock is based on device/inode pairs).

       The name of the directory for making locks.
		 If your system does not have the syscall, then this directory is used when creating locks.  If  the  value  is  empty,  then  the
		 directory of the file to be locked is used.

       The pathname to the
		 program.

       The name of the system-wide default
		 file.	See for the details.

       The highest user-id which should NOT receive mail addressed to
		 everyone.

       If set, then each user-id greater than everyone
		 that  has  a login shell equivalent to the given value (for example, indicates that mail for everyone should not be sent to them.
		 This is useful for handling admin, dummy, and guest logins.

       A few words on locking: MH has a flexible locking system for making locks on files.  There are two variables you should be aware of:  lock-
       style and lockldir.  The first controls the method of locking: the second says where lock files should be created.

       The lockstyle variable can take on three values: 0, 1, 2.  A value of 0 means use the syscall if you are running on 4.2BSD, otherwise use a
       locking style of 1.  A value of 1 or 2 specifies that a file should be created whose existence means locked and whose  non-existence  means
       unlocked.  A value of 1 specified that the lockname is constructed by appending to the name of the file being locked.

       A  value of 2 says to construct the lockname by looking at the device and inode numbers of the file being locked.  If the lockldir variable
       is not specified, lock files will be created in the directory where the file being locked resides.  Otherwise, lock files will  be  created
       in  the	directory specified by lockldir.  Prior to installing MH, you should see how locking is done at your site, and set the appropriate
       values.
