NAME    [Toc]    [Back]

       mail_intro  -  Introductory  information on the Tru64 UNIX
       mail system

DESCRIPTION    [Toc]    [Back]

       The Tru64 UNIX mail system enables you  to  exchange  mail
       with  other  users  on  your system, as well as with other
       systems connected to your local network and with users  on
       other  networks (provided your system and network are connected
 to other networks).

   Mail System Concepts    [Toc]    [Back]
       Mail systems consist of  the  following  components:  User
       agent  -  The  user  agent  provides the interface through
       which you interact with the mail system.   Generally,  the
       user interface enables you to create, send, receive, read,
       save, and manage your mail messages.

              Tru64 UNIX  provides  the  following  user  agents:
              CDE's  Mailer  -  For  further information, see the
              Common Desktop Environment: User's Guide .  Mail or
              mailx  -  For  further information, see the Command
              and Shell User's Guide.  The Rand Message  Handling
              program  (MH)  -  For  further information, see the
              mh(1) and xmh(1X) reference pages.  Transport agent
              - The transport agent provides an interface between
              the user agents and the delivery agents.  The sendmail
 command is a transfer agent.  Delivery agent -
              The  delivery  agent  provides  the  mechanism  for
              delivering the mail messages to end users, systems,
              and networks.  The binmail and deliver commands are
              delivery  agents  for  standard mail and IMAP mail,

       In Tru64 UNIX, the  sendmail  program  acts  as  both  the
       transport  and  delivery agent. It does so by implementing
       the Simple Mail Transfer Protocol  (SMTP),  which  is  the
       specification for the Internet's delivery agent.

       Initially  standards  did not exist for mail addresses and
       computer networks.  Many  different  address  formats  and
       network protocols exist.  Mail programs must interact with
       different network protocols,  as  well  as  recognize  and
       reformat  different  mail  address  formats.  Fortunately,
       these difficulties were recognized and standards, such  as
       the Standard for the Format of ARPA Internet Text Messages
       (RFC 822) and The Domain Naming  Convention  for  Internet
       User  Applications  (RFC  819),  emerged.   A mail program
       still must recognize addresses in various formats and communicate
  with  different  network protocols. The sendmail
       program addresses these issues  through  the  use  of  the
       sendmail.cf configuration file.

   The Sendmail Configuration File    [Toc]    [Back]
       The  sendmail.cf  configuration file provides the sendmail
       program with the  information  to  perform  the  following
       tasks:  Choose delivery agents Use address rewriting rules
       Define mail header information Perform some routing

       When it starts, the sendmail program reads the sendmail.cf
       configuration  file.   The  information in the sendmail.cf
       configuration  file  enables  sendmail  to   rewrite   the
       addresses  of  mail  it  receives  into  the  address form
       expected by the mail delivery agent. It also enables sendmail
  to set parameters and arguments to the mail delivery

       The configuration file contains information that  is  used
       for the following functions: Define message precedence for
       mail delivery Define administrative IDs  to  override  the
       sender's  address  Define message headings Define the mail
       program to use Set options used by the sendmail command

       The default Tru64  UNIX  configuration  file  (located  in
       /var/adm/sendmail/sendmail.cf)  is adequate for most standalone
 systems.  However, if you plan to connect your system
  to a network, you will have to modify the sendmail.cf

       Tru64 UNIX provides the mailconfig  and  mailsetup  utilities,
  which  you  can  use  to  create mail configuration
       files. If you prefer to manipulate the configuration  file
       manually,  you  should use the m4 macros provided for this
       purpose. (See the sendmail.m4(8) reference page.)

       For more information on configuring mail, see the  Network
       Administration: Services manual.
