mtstailor(4)mtstailor(4)NAMEmtstailor - System customization for MH message system
The file /usr/lib/mh/mtstailor defines run-time options for those MH
programs that interact in some form with the message transport system.
At present, these (user) programs are: ap, conflict, inc, msgchk, msh,
post, rcvdist, and rcvpack.
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, MH queries the system for this value (for example: gethost‐
name). This has no equivalent in the MH configuration file. The name
of the local host in the UUCP “domain”. If not set, MH queries the
system for this value. This has no equivalent in the MH configuration
file. A host or list of hosts running sendmail can be specified. When
an MH program is run, it uses this entry to search for a central send‐
mail to connect to. This is particularly useful for workstation users
who may not have sendmail 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, support for MMailids in /etc/passwd is enabled. The
pw_gecos field in the password file is of the form My Full Name
The MH internal routines that deal with user and full names
return mailid and My Full Name respectively. The locking disci‐
pline to perform. A value of 0 or 4 means to use lockf. A
value of 1 means to use BellMail locking always (the name of the
lock is based on the file name). A value of 2 means to use MMDF
locking always (the name of the lock is based on device/inode
pairs); supported only within MH. A value of 5 means to use both
lockf and BellMail style locking (the default).
Note that this locking is superseded by the locking set, if any,
in the rc.config.common file. For more information, see
mail_manual_setup(7). The name of the directory for making
locks when using MMDF style locking. If the value is empty, the
directory of the file to be locked is used. The pathname to the
sendmail program. The name of the system-wide default .mailde‐
livery file. See slocal(1) for the details. The highest user-
id that should NOT receive mail addressed to everyone. All
login names with a user ID greater than the specified value are
included in the address list for the alias. If set, each user-
id greater than everyone that has a login shell equivalent to
the given value (for example, /bin/csh) should not receive mail
addressed to everyone. This is useful for handling admin,
dummy, and guest logins.
MH has a flexible locking system for making locks on files. Two
mtstailor variables pertain to locking: lockstyle and lockldir. The
first controls the method of locking; the second specifies where lock
files should be created.
The lockstyle variable can have one of the following values: Specifies
the lockf system call style locking. Specifies that a file should be
created whose existence means locked and whose non-existence means
unlocked. The lockname is constructed by appending .lock to the name
of the file being locked. Specifies that a file should be created
whose existence means locked and whose non-existence means unlocked.
The lockname is constructed by looking at the device and inode numbers
of the file being locked. If the lockldir variable is not specified,
lock files are created in the directory where the file being locked
resides. Otherwise, lock files are created in the directory specified
by lockldir. Specifies the lockf system call style locking. Specifies
both lockf and BellMail style locking (the default).
Prior to installing MH, you should see how locking is done at your
site, and set the appropriate values.
