  mailsetup - Configures the host's mail system


  /usr/sbin/mailsetup [-f file]


  -f file
      Specifies	the name of the	resulting configuration	file.


  The mailsetup	script sets up the sendmail system on your host. You can use
  this script to do a quick setup where	defaults are used or to	do a more
  extensive setup. Alternatively, you can use the mailconfig command.

  Before you run the mailsetup script, your machine should be established on
  a local area network (LAN). If you want to use domain-based addressing, you
  must also configure the Berkeley Internet Name Domain	(BIND) service in
  your environment. Furthermore, if you	want to	distribute your
  /var/adm/sendmail/aliases database (see aliases(4)) amongst the machines in
  your environment, you	must configure the Network Information Service (NIS).
  See the Network Administration: Services manual, bind_intro(7), and
  nis_intro(7) for more	information about the BIND and NIS services.

  For a	quick setup, the only information you are asked	for is the name	of
  the mail relay you are using and which users are considered local.  For the
  more extensive setup,	you are	asked for the same information in addition to
  UUCP,	DECnet,	and UMC	configuration information, mail	aliases	for your
  machine, local address formats, and other domain information.

  You must run the mailsetup script as superuser and with the system in	mul-
  tiuser mode.

  When you run mailsetup a menu	is displayed giving you	a choice of
  responses.  You are then prompted for	further	information.

  If you do not	use the	-f option, before mailsetup exits, it asks if you
  wish to restart your mail with this new configuration.  If you answer	no,
  your configuration file is saved in /var/adm/sendmail/sendmail.cf.tmp	and
  the install is aborted. If you answer	yes, your
  /var/adm/sendmail/sendmail.cf	file is	moved to
  /var/adm/sendmail/sendmail.cf.orig, if no file by this name exists.  If
  /var/adm/sendmail/sendmail.cf.orig exists, /var/adm/sendmail/sendmail.cf is
  moved	to /var/adm/sendmail/sendmail.cf.n, where n is the version number (0
  to 6 where 0 is the most recent).  The new configuration file	is then	moved
  to /var/adm/sendmail/sendmail.cf and sendmail	is restarted.

  If you use the -f option, the	configuration file is saved with the file
  name specified and sendmail is not restarted.

  The mailsetup	script produces	the following three files in

    +  sendmail.m4

    +  hostname.m4

    +  Makefile.cf.hostname

  You can fine tune your configuration by modifying the	hostname.m4 file and
  issuing a make -f Makefile.cf.hostname command, which	produces a
  hostname.cf file. You	can then copy the hostname.cf file to sendmail.cf and
  restart sendmail using the /sbin/init.d/sendmail restart command.

  Running mailsetup

  To set up your mail system using the mailsetup script, log in	as root	and
  complete the following steps:

   1.  Invoke the mailsetup script.

   2.  The script asks whether you want	to do a	quick setup. If	you answer
       yes, the	mailsetup script prompts you for the following information:

	 +  The	name of	the general-purpose relay

	 +  If you want	to modify the list of aliases and users	that are con-
	    sidered local

	 +  If you want	to complete the	mail setup

       To do an	advanced mail setup, answer no.	 The mailsetup script prompts
       you for the information you collected on	the worksheet.

   3.  When you	finish providing the information, the mailsetup	script asks
       if you want to complete the configuration. If you answer	yes, the
       script moves the	new sendmail.cf	file to	the system space, saves	the
       old sendmail.cf file, and restarts sendmail. If you answer no, the
       script moves the	new sendmail.cf	file to
       /var/adm/sendmail/sendmail.cf.tmp and exits.

  Running mailsetup in a TruCluster Server Cluster

  The following	restrictions apply to setting up mail with the mailsetup
  script in a TruCluster Server	cluster:

    +  You can run the mailsetup script	on an entire cluster, but not focused
       on any one cluster member. If you try to	run mailsetup with the -focus
       option, you will	see the	following error	message:
	    Mail can only be configured	for the	entire cluster.

    +  The cluster members and the cluster alias are added to the Cw macro,
       which defines the nicknames for the cluster. If you delete the cluster
       members or the cluster alias from the nicknames list via	the mailsetup
       script, they are	added again.

       If you do a quick setup with the	mailsetup script, the cluster members
       and the cluster alias are automically added to the Cw macro (nicknames
       list) and you are not prompted to update	the list of nicknames.

    +  Any file	that includes the hostname string as part of the file name is
       changed to includecluster_alias.	For example, hostname.m4 becomes
       cluster_alias.m4	and Makefile.cf.hostname becomes


      Contains alias definitions for the sendmail program.

      Specifies	the users who should receive mail on the local host.

      Specifies	the sendmail configuration file.

      Specifies	the mail setup product description for the configuration

      Specifies	the backup configuration files.

      Specifies	the original configuration file.

      Specifies	the configuration file produced	by mailsetup.

      Specifies	the user configurable file produced by mailsetup. In a Tru-
      Cluster Server cluster, this file	is named after the cluster alias,
      i.e., cluster_alias.m4.

      Specifies	the Makefile file produced by mailsetup	and used to make a
      hostname.cf file from the	sendmail.cf and	hostname.m4 files. In a	Tru-
      Cluster Server cluster, this file	is named after the cluster alias,
      i.e., Makefile.cf.cluster_alias.
