NAME

       sendmail - Postfix to Sendmail compatibility interface

SYNOPSIS

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

       mailq
       sendmail -bp

       newaliases
       sendmail -I

DESCRIPTION

       The  Postfix  sendmail(1)  command  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, Postfix sendmail(1) reads a  message  from  standard  input
       until  EOF  or  until  it  reads  a  line  with only a . character, and
       arranges for delivery.  Postfix sendmail(1) relies on  the  postdrop(1)
       command to create a queue file in the maildrop directory.

       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. The queue ID string is
              followed by an optional status character:

              *      The message is in the active queue, i.e. the  message  is
                     selected for delivery.

              !      The  message  is  in  the  hold  queue,  i.e.  no further
                     delivery attempt will be made until the mail is taken off
                     hold.

              This   mode   of  operation  is  implemented  by  executing  the
              postqueue(1) command.

       newaliases
              Initialize the alias database.  If no input  file  is  specified
              (with  the  -oA  option,  see  below), the program processes the
              file(s)  specified   with   the   alias_database   configuration
              parameter.   If no alias database type is specified, the program
              uses  the  type   specified   with   the   default_database_type
              configuration  parameter.  This mode of operation is implemented
              by running the postalias(1) command.

              Note: it may take a minute or so before an alias database update
              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 features are controlled by
       parameters in the main.cf configuration file.

       The following options are recognized:

       -Am (ignored)

       -Ac (ignored)
              Postfix sendmail uses the same configuration file regardless  of
              whether or not a message is an initial submission.

       -B body_type
              The message body MIME type: 7BIT or 8BITMIME.

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

       -bh (ignored)

       -bH (ignored)
              Postfix has no persistent host status database.

       -bi    Initialize alias database. See the newaliases command 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 standard output.   In  stand-alone
              SMTP  server  mode,  mail relaying and other access controls are
              disabled by default. To enable them,  run  the  process  as  the
              mail_owner user.

              This  mode  of  operation is implemented by running the smtpd(8)
              daemon.

       -bv    Do not collect or deliver a  message.  Instead,  send  an  email
              report  after  verifying each recipient address.  This is useful
              for testing address rewriting and routing configurations.

              This feature is available in Postfix version 2.1 and later.

       -C config_file

       -C config_dir
              The path name of the Postfix main.cf  file,  or  of  its  parent
              directory.  This  information  is  ignored with Postfix versions
              before 2.3.

              With all Postfix versions, you can specify a directory  pathname
              with  the  MAIL_CONFIG  environment  variable  to  override  the
              location of configuration files.

       -F full_name
              Set the sender full name. This overrides  the  NAME  environment
              variable,  and  is  used  only  with messages that have no From:
              message header.

       -f sender
              Set the envelope sender  address.  This  is  the  address  where
              delivery problems are sent to. With Postfix versions before 2.1,
              the  Errors-To:  message  header  overrides  the  error   return
              address.

       -G     Gateway   (relay)   submission,   as  opposed  to  initial  user
              submission.  Either do not rewrite addresses at all,  or  update
              incomplete  addresses with the domain information specified with
              remote_header_rewrite_domain.

              This option is ignored before Postfix version 2.3.

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

       -I     Initialize alias database. See the newaliases command above.

       -i     When  reading  a message from standard input, don't treat a line
              with only a . character as the end of input.

       -L label (ignored)
              The logging label. Use the syslog_name  configuration  parameter
              instead.

       -m (ignored)
              Backwards compatibility.

       -N dsn (default: 'delay, failure')
              Delivery  status  notification  control. Specify either a comma-
              separated list with one or more of  failure  (send  notification
              when  delivery fails), delay (send notification when delivery is
              delayed), or success (send  notification  when  the  message  is
              delivered);  or  specify  never (don't send any notifications at
              all).

              This feature is available in Postfix 2.3 and later.

       -n (ignored)
              Backwards compatibility.

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

       -O option=value (ignored)
              Backwards compatibility.

       -o7 (ignored)

       -o8 (ignored)
              To  send  8-bit  or  binary  content,  use  an  appropriate MIME
              encapsulation  and  specify  the  appropriate  -B   command-line
              option.

       -oi    When  reading  a message from standard input, don't treat a line
              with only a . character as the end of input.

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

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

       -r sender
              Set  the  envelope  sender  address.  This  is the address where
              delivery problems are sent to. With Postfix versions before 2.1,
              the   Errors-To:  message  header  overrides  the  error  return
              address.

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

       -q     Attempt  to  deliver  all  queued  mail.  This is implemented by
              executing the postqueue(1) command.

              Warning: flushing undeliverable mail frequently will  result  in
              poor delivery performance of all other mail.

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

       -qIqueueid
              Schedule immediate delivery of mail with the specified queue ID.
              This   option  is  implemented  by  executing  the  postqueue(1)
              command, and is available with Postfix version 2.4 and later.

       -qRsite
              Schedule immediate delivery of all mail that is queued  for  the
              named  site.  This  option  accepts  only  site  names  that are
              eligible for the "fast flush" service,  and  is  implemented  by
              executing  the  postqueue(1)  command.   See  flush(8)  for more
              information about the "fast flush" service.

       -qSsite
              This command is not implemented. Use the  slower  "sendmail  -q"
              command instead.

       -t     Extract  recipients from message headers. These are added to any
              recipients specified on the command line.

              With Postfix versions prior to 2.1, this option requires that no
              recipient addresses are specified on the command line.

       -U (ignored)
              Initial user submission.

       -V envid
              Specify the envelope ID for notification by servers that support
              DSN.

              This feature is available in Postfix 2.3 and later.

       -XV (Postfix 2.2 and earlier: -V)
              Variable Envelope Return Path. Given an envelope sender  address
              of  the  form  owner-listname@origin, each recipient user@domain
              receives mail with a personalized envelope sender address.

              By default, the personalized envelope sender address  is  owner-
              listname+user=domain@origin.  The default + and = characters are
              configurable  with  the  default_verp_delimiters   configuration
              parameter.

       -XVxy (Postfix 2.2 and earlier: -Vxy)
              As  -XV,  but  uses  x  and  y as the VERP delimiter characters,
              instead    of    the    characters    specified     with     the
              default_verp_delimiters configuration parameter.

       -v     Send  an  email  report  of  the first delivery attempt (Postfix
              versions 2.1 and later). Mail delivery  always  happens  in  the
              background.  When  multiple -v options are given, enable verbose
              logging for debugging purposes.

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

SECURITY

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

DIAGNOSTICS
