+.SH DESCRIPTION
+.ad
+.fi
+The Postfix \fBsendmail\fR(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 \fBsendmail\fR(1) reads a message from
+standard input
+until EOF or until it reads a line with only a \fB.\fR character,
+and arranges for delivery.  Postfix \fBsendmail\fR(1) relies on the
+\fBpostdrop\fR(1) command to create a queue file in the \fBmaildrop\fR
+directory.
+
+Specific command aliases are provided for other common modes of
+operation:
+.IP \fBmailq\fR
+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:
+.RS
+.IP \fB*\fR
+The message is in the \fBactive\fR queue, i.e. the message is
+selected for delivery.
+.IP \fB!\fR
+The message is in the \fBhold\fR queue, i.e. no further delivery
+attempt will be made until the mail is taken off hold.
+.RE
+.IP
+This mode of operation is implemented by executing the
+\fBpostqueue\fR(1) command.
+.IP \fBnewaliases\fR
+Initialize the alias database.  If no input file is specified (with
+the \fB\-oA\fR option, see below), the program processes the file(s)
+specified with the \fBalias_database\fR configuration parameter.
+If no alias database type is specified, the program uses the type
+specified with the \fBdefault_database_type\fR configuration parameter.
+This mode of operation is implemented by running the \fBpostalias\fR(1)
+command.
+.sp
+Note: it may take a minute or so before an alias database update
+becomes visible. Use the "\fBpostfix reload\fR" command to eliminate
+this delay.
+.PP
+These and other features can be selected by specifying the
+appropriate combination of command\-line options. Some features are
+controlled by parameters in the \fBmain.cf\fR configuration file.
+
+The following options are recognized:
+.IP "\fB\-Am\fR (ignored)"
+.IP "\fB\-Ac\fR (ignored)"
+Postfix sendmail uses the same configuration file regardless of
+whether or not a message is an initial submission.
+.IP "\fB\-B \fIbody_type\fR"
+The message body MIME type: \fB7BIT\fR or \fB8BITMIME\fR.
+.IP \fB\-bd\fR
+Go into daemon mode. This mode of operation is implemented by
+executing the "\fBpostfix start\fR" command.
+.IP "\fB\-bh\fR (ignored)"
+.IP "\fB\-bH\fR (ignored)"
+Postfix has no persistent host status database.
+.IP \fB\-bi\fR
+Initialize alias database. See the \fBnewaliases\fR
+command above.
+.IP \fB\-bl\fR
+Go into daemon mode. To accept only local connections as
+with Sendmail\'s \fB\-bl\fR option, specify "\fBinet_interfaces
+= loopback\fR" in the Postfix \fBmain.cf\fR configuration
+file.
+.IP \fB\-bm\fR
+Read mail from standard input and arrange for delivery.
+This is the default mode of operation.
+.IP \fB\-bp\fR
+List the mail queue. See the \fBmailq\fR command above.
+.IP \fB\-bs\fR
+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 \fBmail_owner\fR user.
+.sp
+This mode of operation is implemented by running the
+\fBsmtpd\fR(8) daemon.
+.IP \fB\-bv\fR
+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.
+.sp
+This feature is available in Postfix version 2.1 and later.
+.IP "\fB\-C \fIconfig_file\fR"
+.IP "\fB\-C \fIconfig_dir\fR"
+The path name of the Postfix \fBmain.cf\fR file, or of its
+parent directory. This information is ignored with Postfix
+versions before 2.3.
+
+With Postfix version 3.2 and later, a non\-default directory
+must be authorized in the default \fBmain.cf\fR file, through
+the alternate_config_directories or multi_instance_directories
+parameters.
+
+With all Postfix versions, you can specify a directory pathname
+with the MAIL_CONFIG environment variable to override the
+location of configuration files.
+.IP "\fB\-F \fIfull_name\fR"
+Set the sender full name. This overrides the NAME environment
+variable, and is used only with messages that
+have no \fBFrom:\fR message header.
+.IP "\fB\-f \fIsender\fR"
+Set the envelope sender address. This is the address where
+delivery problems are sent to. With Postfix versions before 2.1, the
+\fBErrors\-To:\fR message header overrides the error return address.
+.IP \fB\-G\fR
+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 \fBremote_header_rewrite_domain\fR.
+
+This option is ignored before Postfix version 2.3.
+.IP "\fB\-h \fIhop_count\fR (ignored)"
+Hop count limit. Use the \fBhopcount_limit\fR configuration
+parameter instead.
+.IP \fB\-I\fR
+Initialize alias database. See the \fBnewaliases\fR
+command above.
+.IP "\fB\-i\fR"
+When reading a message from standard input, don\'t treat a line
+with only a \fB.\fR character as the end of input.
+.IP "\fB\-L \fIlabel\fR (ignored)"
+The logging label. Use the \fBsyslog_name\fR configuration
+parameter instead.
+.IP "\fB\-m\fR (ignored)"
+Backwards compatibility.
+.IP "\fB\-N \fIdsn\fR (default: 'delay, failure')"
+Delivery status notification control. Specify either a
+comma\-separated list with one or more of \fBfailure\fR (send
+notification when delivery fails), \fBdelay\fR (send
+notification when delivery is delayed), or \fBsuccess\fR
+(send notification when the message is delivered); or specify
+\fBnever\fR (don't send any notifications at all).
+
+This feature is available in Postfix 2.3 and later.
+.IP "\fB\-n\fR (ignored)"
+Backwards compatibility.
+.IP "\fB\-oA\fIalias_database\fR"
+Non\-default alias database. Specify \fIpathname\fR or
+\fItype\fR:\fIpathname\fR. See \fBpostalias\fR(1) for
+details.
+.IP "\fB\-O \fIoption=value\fR (ignored)"
+Set the named \fIoption\fR to \fIvalue\fR. Use the equivalent
+configuration parameter in \fBmain.cf\fR instead.
+.IP "\fB\-o7\fR (ignored)"
+.IP "\fB\-o8\fR (ignored)"
+To send 8\-bit or binary content, use an appropriate MIME encapsulation
+and specify the appropriate \fB\-B\fR command\-line option.
+.IP "\fB\-oi\fR"
+When reading a message from standard input, don\'t treat a line
+with only a \fB.\fR character as the end of input.
+.IP "\fB\-om\fR (ignored)"
+The sender is never eliminated from alias etc. expansions.
+.IP "\fB\-o \fIx value\fR (ignored)"
+Set option \fIx\fR to \fIvalue\fR. Use the equivalent
+configuration parameter in \fBmain.cf\fR instead.
+.IP "\fB\-r \fIsender\fR"
+Set the envelope sender address. This is the address where
+delivery problems are sent to. With Postfix versions before 2.1, the
+\fBErrors\-To:\fR message header overrides the error return address.
+.IP "\fB\-R \fIreturn\fR"
+Delivery status notification control.  Specify "hdrs" to
+return only the header when a message bounces, "full" to
+return a full copy (the default behavior).
+
+The \fB\-R\fR option specifies an upper bound; Postfix will
+return only the header, when a full copy would exceed the
+bounce_size_limit setting.
+
+This option is ignored before Postfix version 2.10.
+.IP \fB\-q\fR
+Attempt to deliver all queued mail. This is implemented by
+executing the \fBpostqueue\fR(1) command.
+
+Warning: flushing undeliverable mail frequently will result in
+poor delivery performance of all other mail.
+.IP "\fB\-q\fIinterval\fR (ignored)"
+The interval between queue runs. Use the \fBqueue_run_delay\fR
+configuration parameter instead.
+.IP \fB\-qI\fIqueueid\fR
+Schedule immediate delivery of mail with the specified queue
+ID.  This option is implemented by executing the
+\fBpostqueue\fR(1) command, and is available with Postfix
+version 2.4 and later.
+.IP \fB\-qR\fIsite\fR
+Schedule immediate delivery of all mail that is queued for the named
+\fIsite\fR. This option accepts only \fIsite\fR names that are
+eligible for the "fast flush" service, and is implemented by
+executing the \fBpostqueue\fR(1) command.
+See \fBflush\fR(8) for more information about the "fast flush"
+service.
+.IP \fB\-qS\fIsite\fR
+This command is not implemented. Use the slower "\fBsendmail \-q\fR"
+command instead.
+.IP \fB\-t\fR
+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.
+.IP "\fB\-U\fR (ignored)"
+Initial user submission.
+.IP "\fB\-V \fIenvid\fR"
+Specify the envelope ID for notification by servers that
+support DSN.
+
+This feature is available in Postfix 2.3 and later.
+.IP "\fB\-XV\fR (Postfix 2.2 and earlier: \fB\-V\fR)"
+Variable Envelope Return Path. Given an envelope sender address
+of the form \fIowner\-listname\fR@\fIorigin\fR, each recipient
+\fIuser\fR@\fIdomain\fR receives mail with a personalized envelope
+sender address.
+.sp
+By default, the personalized envelope sender address is
+\fIowner\-listname\fB+\fIuser\fB=\fIdomain\fR@\fIorigin\fR. The default
+\fB+\fR and \fB=\fR characters are configurable with the
+\fBdefault_verp_delimiters\fR configuration parameter.
+.IP "\fB\-XV\fIxy\fR (Postfix 2.2 and earlier: \fB\-V\fIxy\fR)"
+As \fB\-XV\fR, but uses \fIx\fR and \fIy\fR as the VERP delimiter
+characters, instead of the characters specified with the
+\fBdefault_verp_delimiters\fR configuration parameter.
+.IP \fB\-v\fR
+Send an email report of the first delivery attempt (Postfix
+versions 2.1 and later). Mail delivery
+always happens in the background. When multiple \fB\-v\fR
+options are given, enable verbose logging for debugging purposes.
+.IP "\fB\-X \fIlog_file\fR (ignored)"
+Log mailer traffic. Use the \fBdebug_peer_list\fR and
+\fBdebug_peer_level\fR configuration parameters instead.
