mtstailor - 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: gethostname). 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 sendmail
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 <mailid>
The MH internal routines that deal with user and
full names return mailid and My Full Name respectively.
The locking discipline 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Note that this locking is superseded by the locking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 .maildelivery 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.
Locking [Toc] [Back]
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.
