<b><a name="description">DESCRIPTION</a></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')
|
|

|
|
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>.

|
|
|
|
<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.
|
|
|

The sender is never eliminated from alias etc. expansions.
|
|
|
|
<b>-o</b> <i>x value</i> (ignored)

|
|
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><a name="security">SECURITY</a></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>".
