NAME
       sendmail - Postfix to Sendmail compatibility interface

SYNOPSIS
       sendmail [option ...] [recipient ...]

       mailq
       sendmail -bp

       newaliases
       sendmail -I

DESCRIPTION
       The  sendmail  program  implements the Postfix to Sendmail
       compatibility interface.  For the  sake  of  compatibility
       with  existing  applications,  some  Sendmail command-line
       options are recognized but silently ignored.

       By default, sendmail reads a message from  standard  input
       and  arranges  for delivery.  Specific command aliases are
       provided for other common modes of operation:

       mailq  List the mail queue. Each  entry  shows  the  queue
              file  ID,  message  size, arrival time, sender, and
              the recipients that still need to be delivered.  If
              mail  could not be delivered upon the last attempt,
              the reason for failure is shown. This mode of oper-
              ation  is implemented by connecting to the showq(8)
              daemon.

       newaliases
              Initialize the alias database. If no alias database
              type is specified, the program uses the type speci-
              fied in the database_type configuration  parameter;
              if  no  input  file is specified, the program reads
              the file specified with the alias_database configu-
              ration  parameter. This mode of operation is imple-
              mented by running the postalias(1) command.

              Note: it may take a minute or so  before  an  alias
              database  becomes  visible.  Use the postfix reload
              command to eliminate this delay.

       These and other features can be selected by specifying the
       appropriate combination of command-line options. Some fea-
       tures are controlled by parameters in the main.cf configu-
       ration file.

       The following options are recognized:

       -B body_type (ignored)
              The  message  body  MIME  type.  Currently, Postfix
              implements just-send-eight.




                                                                1





SENDMAIL(1)                                           SENDMAIL(1)


       -C config_file (ignored :-)
              The path name of the sendmail.cf file. Postfix con-
              figuration files are kept in /etc/postfix.

       -F full_name
              Set  the  sender  full name. This is used only with
              messages that have no From: message header.

       -I     Initialize alias database. See the newaliases  com-
              mand above.

       -N dsn (ignored)
              Delivery  status  notification  control. Currently,
              Postfix does not implement DSN.

       -R return_limit (ignored)
              Limit  the  size   of   bounced   mail.   Use   the
              bounce_size_limit  configuration parameter instead.

       -X log_file (ignored)
              Log mailer traffic.  Use  the  debug_peer_list  and
              debug_peer_level  configuration parameters instead.

       -bd    Go into daemon mode.  This  mode  of  operation  is
              implemented by executing the postfix start command.

       -bi    Initialize alias database. See the newaliases  com-
              mand above.

       -bm    Read  mail  from  standard  input  and  arrange for
              delivery.  This is the default mode of operation.

       -bp    List the mail queue. See the mailq command above.

       -bs    Stand-alone SMTP server mode.  Read  SMTP  commands
              from  standard  input, and write responses to stan-
              dard output.  This mode of operation is implemented
              by running the smtpd(8) daemon.

       -f sender
              Set  the  envelope  sender  address.  This  is  the
              address where delivery problems are sent to, unless
              the  message contains an Errors-To: message header.

       -h hop_count (ignored)
              Hop count limit. Use the hopcount_limit  configura-
              tion parameter instead.

       -i (ignored)
              Lines beginning with "." get special treatment only
              with -bs.

       -m (ignored)
              Backwards compatibility.



                                                                2





SENDMAIL(1)                                           SENDMAIL(1)


       -n (ignored)
              Backwards compatibility.

       -oAalias_database
              Non-default alias  database.  Specify  pathname  or
              type:pathname. See postalias(1) for details.

       -o7 (ignored)

       -o8 (ignored)
              The  message  body  type. Currently, Postfix imple-
              ments just-send-eight.

       -om (ignored)
              The sender is  never  eliminated  from  alias  etc.
              expansions.

       -o x value (ignored)
              Set  option x to value. Use the equivalent configu-
              ration parameter in main.cf instead.

       -q     Flush the mail queue. This is implemented by  kick-
              ing the qmgr(8) daemon.

       -qinterval (ignored)
              The   interval   between   queue   runs.   Use  the
              queue_run_delay configuration parameter instead.

       -t     Extract  recipients  from  message  headers.   This
              requires  that  no  recipients  be specified on the
              command line.

       -v     Enable verbose logging for debugging purposes. Mul-
              tiple  -v  options  make  the software increasingly
              verbose.

SECURITY
       By design, this program is not  set-user  (or  group)  id.
       However,  it  must  handle  data  from  untrusted users or
       untrusted machines.  Thus, the usual precautions  need  to
       be taken against malicious inputs.

DIAGNOSTICS
       Problems  and  transactions  are logged to syslogd(8).  If
       the standard error stream is  a  terminal,  some  problems
       will be logged there as well.

ENVIRONMENT
       MAIL_CONFIG
              Directory with Postfix configuration files.

       MAIL_VERBOSE
              Enable verbose logging




                                                                3
