+SENDMAIL(1) SENDMAIL(1)
+
+<b>NAME</b>
+ sendmail - Postfix to Sendmail compatibility interface
+
+<b>SYNOPSIS</b>
+ <b>sendmail</b> [<i>option ...</i>] [<i>recipient ...</i>]
+
+ <b>mailq</b>
+ <b>sendmail -bp</b>
+
+ <b>newaliases</b>
+ <b>sendmail -I</b>
+
+<b>DESCRIPTION</b>
+ The Postfix <a href="sendmail.1.html"><b>sendmail</b>(1)</a> command implements the Postfix to Sendmail com-
+ patibility interface. For the sake of compatibility with existing
+ applications, some Sendmail command-line options are recognized but
+ silently ignored.
+
+ By default, Postfix <a href="sendmail.1.html"><b>sendmail</b>(1)</a> reads a message from standard input
+ until EOF or until it reads a line with only a <b>.</b> character, and
+ arranges for delivery. Postfix <a href="sendmail.1.html"><b>sendmail</b>(1)</a> relies on the <a href="postdrop.1.html"><b>postdrop</b>(1)</a>
+ command to create a queue file in the <b>maildrop</b> directory.
+
+ Specific command aliases are provided for other common modes of opera-
+ tion:
+
+ <b>mailq</b> 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:
+
+ <b>*</b> The message is in the <b>active</b> queue, i.e. the message is
+ selected for delivery.
+
+ <b>!</b> The message is in the <b>hold</b> queue, i.e. no further deliv-
+ ery attempt will be made until the mail is taken off
+ hold.
+
+ <b>#</b> The message is forced to expire. See the <a href="postsuper.1.html"><b>postsuper</b>(1)</a>
+ options <b>-e</b> or <b>-f</b>.
+
+ This mode of operation is implemented by executing the
+ <a href="postqueue.1.html"><b>postqueue</b>(1)</a> command.
+
+ <b>newaliases</b>
+ Initialize the alias database. If no input file is specified
+ (with the <b>-oA</b> option, see below), the program processes the
+ file(s) specified with the <b><a href="postconf.5.html#alias_database">alias_database</a></b> configuration parame-
+ ter. If no alias database type is specified, the program uses
+ the type specified with the <b><a href="postconf.5.html#default_database_type">default_database_type</a></b> configuration
+ parameter. This mode of operation is implemented by running the
+ <a href="postalias.1.html"><b>postalias</b>(1)</a> command.
+
+ Note: it may take a minute or so before an alias database update
+ becomes visible. Use the "<b>postfix reload</b>" 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 <a href="postconf.5.html"><b>main.cf</b></a> configuration file.
+
+ The following options are recognized:
+
+ <b>-Am</b> (ignored)
+
+ <b>-Ac</b> (ignored)
+ Postfix sendmail uses the same configuration file regardless of
+ whether or not a message is an initial submission.
+
+ <b>-B</b> <i>body</i><b>_</b><i>type</i>
+ The message body MIME type: <b>7BIT</b> or <b>8BITMIME</b>.
+
+ <b>-bd</b> Go into daemon mode. This mode of operation is implemented by
+ executing the "<b>postfix start</b>" command.
+
+ <b>-bh</b> (ignored)
+
+ <b>-bH</b> (ignored)
+ Postfix has no persistent host status database.
+
+ <b>-bi</b> Initialize alias database. See the <b>newaliases</b> command above.
+
+ <b>-bl</b> Go into daemon mode. To accept only local connections as with
+ Sendmail's <b>-bl</b> option, specify "<b><a href="postconf.5.html#inet_interfaces">inet_interfaces</a> = loopback</b>" in
+ the Postfix <a href="postconf.5.html"><b>main.cf</b></a> configuration file.
+
+ <b>-bm</b> Read mail from standard input and arrange for delivery. This is
+ the default mode of operation.
+
+ <b>-bp</b> List the mail queue. See the <b>mailq</b> command above.
+
+ <b>-bs</b> 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
+ <b><a href="postconf.5.html#mail_owner">mail_owner</a></b> user.
+
+ This mode of operation is implemented by running the <a href="smtpd.8.html"><b>smtpd</b>(8)</a>
+ daemon.
+
+ <b>-bv</b> 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.
+
+ <b>-C</b> <i>config</i><b>_</b><i>file</i>
+
+ <b>-C</b> <i>config</i><b>_</b><i>dir</i>
+ The path name of the Postfix <a href="postconf.5.html"><b>main.cf</b></a> 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 <a href="postconf.5.html"><b>main.cf</b></a> file, through the alter-
+ nate_config_directories or <a href="postconf.5.html#multi_instance_directories">multi_instance_directories</a> parame-
+ ters.
+
+ With all Postfix versions, you can specify a directory pathname
+ with the MAIL_CONFIG environment variable to override the loca-
+ tion of configuration files.
+
+ <b>-F</b> <i>full</i><b>_</b><i>name</i>
+ Set the sender full name. This overrides the NAME environment
+ variable, and is used only with messages that have no <b>From:</b> mes-
+ sage header.
+
+ <b>-f</b> <i>sender</i>
+ Set the envelope sender address. This is the address where
+ delivery problems are sent to. With Postfix versions before 2.1,
+ the <b>Errors-To:</b> message header overrides the error return
+ address.
+
+ <b>-G</b> Gateway (relay) submission, as opposed to initial user submis-
+ sion. Either do not rewrite addresses at all, or update incom-
+ plete addresses with the domain information specified with
+ <b><a href="postconf.5.html#remote_header_rewrite_domain">remote_header_rewrite_domain</a></b>.
+
+ This option is ignored before Postfix version 2.3.
+
+ <b>-h</b> <i>hop</i><b>_</b><i>count</i> (ignored)
+ Hop count limit. Use the <b><a href="postconf.5.html#hopcount_limit">hopcount_limit</a></b> configuration parameter
+ instead.
+
+ <b>-I</b> Initialize alias database. See the <b>newaliases</b> command above.
+
+ <b>-i</b> When reading a message from standard input, don't treat a line
+ with only a <b>.</b> character as the end of input.
+
+ <b>-L</b> <i>label</i> (ignored)
+ The logging label. Use the <b><a href="postconf.5.html#syslog_name">syslog_name</a></b> configuration parameter
+ instead.
+
+ <b>-m</b> (ignored)
+ Backwards compatibility.
+
+ <b>-N</b> <i>dsn</i> (default: 'delay, failure')
+ Delivery status notification control. Specify either a
+ comma-separated list with one or more of <b>failure</b> (send notifica-
+ tion when delivery fails), <b>delay</b> (send notification when deliv-
+ ery is delayed), or <b>success</b> (send notification when the message
+ is delivered); or specify <b>never</b> (don't send any notifications at
+ all).
+
+ This feature is available in Postfix 2.3 and later.
+
+ <b>-n</b> (ignored)
+ Backwards compatibility.
+
+ <b>-oA</b><i>alias</i><b>_</b><i>database</i>
+ Non-default alias database. Specify <i>pathname</i> or <i>type</i>:<i>pathname</i>.
+ See <a href="postalias.1.html"><b>postalias</b>(1)</a> for details.
+
+ <b>-O</b> <i>option=value</i> (ignored)
+ Set the named <i>option</i> to <i>value</i>. Use the equivalent configuration
+ parameter in <a href="postconf.5.html"><b>main.cf</b></a> instead.
+
+ <b>-o7</b> (ignored)
+
+ <b>-o8</b> (ignored)
+ To send 8-bit or binary content, use an appropriate MIME encap-
+ sulation and specify the appropriate <b>-B</b> command-line option.
+
+ <b>-oi</b> When reading a message from standard input, don't treat a line
+ with only a <b>.</b> character as the end of input.
+
+ <b>-om</b> (ignored)
+ The sender is never eliminated from alias etc. expansions.
+
+ <b>-o</b> <i>x value</i> (ignored)
+ Set option <i>x</i> to <i>value</i>. Use the equivalent configuration parame-
+ ter in <a href="postconf.5.html"><b>main.cf</b></a> instead.
+
+ <b>-r</b> <i>sender</i>
+ Set the envelope sender address. This is the address where
+ delivery problems are sent to. With Postfix versions before 2.1,
+ the <b>Errors-To:</b> message header overrides the error return
+ address.
+
+ <b>-R</b> <i>return</i>
+ 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 <b>-R</b> option specifies an upper bound; Postfix will return only
+ the header, when a full copy would exceed the <a href="postconf.5.html#bounce_size_limit">bounce_size_limit</a>
+ setting.
+
+ This option is ignored before Postfix version 2.10.
+
+ <b>-q</b> Attempt to deliver all queued mail. This is implemented by exe-
+ cuting the <a href="postqueue.1.html"><b>postqueue</b>(1)</a> command.
+
+ Warning: flushing undeliverable mail frequently will result in
+ poor delivery performance of all other mail.
+
+ <b>-q</b><i>interval</i> (ignored)
+ The interval between queue runs. Use the <b><a href="postconf.5.html#queue_run_delay">queue_run_delay</a></b> config-
+ uration parameter instead.
+
+ <b>-qI</b><i>queueid</i>
+ Schedule immediate delivery of mail with the specified queue ID.
+ This option is implemented by executing the <a href="postqueue.1.html"><b>postqueue</b>(1)</a> com-
+ mand, and is available with Postfix version 2.4 and later.
+
+ <b>-qR</b><i>site</i>
+ Schedule immediate delivery of all mail that is queued for the
+ named <i>site</i>. This option accepts only <i>site</i> names that are eligi-
+ ble for the "fast flush" service, and is implemented by execut-
+ ing the <a href="postqueue.1.html"><b>postqueue</b>(1)</a> command. See <a href="flush.8.html"><b>flush</b>(8)</a> for more information
+ about the "fast flush" service.
+
+ <b>-qS</b><i>site</i>
+ This command is not implemented. Use the slower "<b>sendmail -q</b>"
+ command instead.
+
+ <b>-t</b> 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.
+
+ <b>-U</b> (ignored)
+ Initial user submission.
+
+ <b>-V</b> <i>envid</i>
+ Specify the envelope ID for notification by servers that support
+ DSN.
+
+ This feature is available in Postfix 2.3 and later.
+
+ <b>-XV</b> (Postfix 2.2 and earlier: <b>-V</b>)
+ Variable Envelope Return Path. Given an envelope sender address
+ of the form <i>owner-listname</i>@<i>origin</i>, each recipient <i>user</i>@<i>domain</i>
+ receives mail with a personalized envelope sender address.
+
+ By default, the personalized envelope sender address is
+ <i>owner-listname</i><b>+</b><i>user</i><b>=</b><i>domain</i>@<i>origin</i>. The default <b>+</b> and <b>=</b> charac-
+ ters are configurable with the <b><a href="postconf.5.html#default_verp_delimiters">default_verp_delimiters</a></b> configu-
+ ration parameter.
+
+ <b>-XV</b><i>xy</i> (Postfix 2.2 and earlier: <b>-V</b><i>xy</i>)
+ As <b>-XV</b>, but uses <i>x</i> and <i>y</i> as the VERP delimiter characters,
+ instead of the characters specified with the <b><a href="postconf.5.html#default_verp_delimiters">default_verp_delim</a>-</b>
+ <b><a href="postconf.5.html#default_verp_delimiters">iters</a></b> configuration parameter.
+
+ <b>-v</b> Send an email report of the first delivery attempt (Postfix ver-
+ sions 2.1 and later). Mail delivery always happens in the back-
+ ground. When multiple <b>-v</b> options are given, enable verbose log-
+ ging for debugging purposes.
+
+ <b>-X</b> <i>log</i><b>_</b><i>file</i> (ignored)
+ Log mailer traffic. Use the <b><a href="postconf.5.html#debug_peer_list">debug_peer_list</a></b> and <b><a href="postconf.5.html#debug_peer_level">debug_peer_level</a></b>
+ configuration parameters instead.
+
+<b>SECURITY</b>
+ By design, this program is not set-user (or group) id. It is prepared
+ to handle message content from untrusted, possibly remote, users.
+
+ However, like most Postfix programs, this program does not enforce a
+ security policy on its command-line arguments. Instead, it relies on
+ the UNIX system to enforce access policies based on the effective user
+ and group IDs of the process. Concretely, this means that running Post-
+ fix commands as root (from sudo or equivalent) on behalf of a non-root
+ user is likely to create privilege escalation opportunities.
+
+ If an application runs any Postfix programs on behalf of users that do
+ not have normal shell access to Postfix commands, then that application
+ MUST restrict user-specified command-line arguments to avoid privilege
+ escalation.
+
+ <b>o</b> Filter all command-line arguments, for example arguments that
+ contain a pathname or that specify a database access method.
+ These pathname checks must reject user-controlled symlinks or
+ hardlinks to sensitive files, and must not be vulnerable to TOC-
+ TOU race attacks.
+
+ <b>o</b> Disable command options processing for all command arguments
+ that contain user-specified data. For example, the Postfix <a href="sendmail.1.html"><b>send-</b></a>
+ <a href="sendmail.1.html"><b>mail</b>(1)</a> command line MUST be structured as follows:
+
+ <b>/path/to/sendmail</b> <i>system-arguments</i> <b>--</b> <i>user-arguments</i>
+
+ Here, the "<b>--</b>" disables command option processing for all
+ <i>user-arguments</i> that follow.
+
+ Without the "<b>--</b>", a malicious user could enable Postfix <a href="sendmail.1.html"><b>send-</b></a>
+ <a href="sendmail.1.html"><b>mail</b>(1)</a> command options, by specifying an email address that
+ starts with "<b>-</b>".
+
+<b>DIAGNOSTICS</b>
+ Problems are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>, and to the standard
+ error stream.
+
+<b>ENVIRONMENT</b>
