To submit mail, use the 17 Postfix <a href="sendmail.1.html"><b>sendmail</b>(1)</a> command. 18 19 The <a href="postfix.1.html"><b>postfix</b>(1)</a> command controls the operation of the Postfix mail sys- 20 tem: start or stop the <a href="master.8.html"><b>master</b>(8)</a> daemon, do a health check, and other 21 maintenance. 22 23 By default, the <a href="postfix.1.html"><b>postfix</b>(1)</a> command sets up a standardized environment 24 and runs the <b>postfix-script</b> shell script to do the actual work. 25 26 However, when support for multiple Postfix instances is configured, 27 <a href="postfix.1.html"><b>postfix</b>(1)</a> executes the command specified with the <b><a href="postconf.5.html#multi_instance_wrapper">multi_instance_wrap</a>-</b> 28 <b><a href="postconf.5.html#multi_instance_wrapper">per</a></b> configuration parameter. This command will execute the <i>command</i> for 29 each applicable Postfix instance. 30 31 The following commands are implemented: 32 33 <b>check</b> Warn about bad directory/file ownership or permissions, and cre- 34 ate missing directories. 35 36 <b>start</b> Start the Postfix mail system. This also runs the configuration 37 check described above. 38 39 <b>start-fg</b> 40 Like <b>start</b>, but keep the <a href="master.8.html"><b>master</b>(8)</a> daemon running in the fore- 41 ground, and enable <a href="master.8.html"><b>master</b>(8)</a> "init" mode when running as PID 1. 42 This command requires that multi-instance support is disabled 43 (i.e. the <a href="postconf.5.html#multi_instance_directories">multi_instance_directories</a> parameter value must be 44 empty). When running Postfix inside a container, mount the con- 45 tainer host's /dev/log socket inside the container (example: 46 "docker run -v /dev/log:/dev/log ...") and specify a distinct 47 Postfix "<a href="postconf.5.html#syslog_name">syslog_name</a>" prefix that identifies logging from the 48 Postfix instance. 49 50 <b>stop</b> Stop the Postfix mail system in an orderly fashion. If possible, 51 running processes are allowed to terminate at their earliest 52 convenience. 53 54 Note: in order to refresh the Postfix mail system after a con- 55 figuration change, do not use the <b>start</b> and <b>stop</b> commands in 56 succession. Use the <b>reload</b> command instead. 57 58 <b>abort</b> Stop the Postfix mail system abruptly. Running processes are 59 signaled to stop immediately. 60 61 <b>flush</b> Force delivery: attempt to deliver every message in the deferred 62 mail queue. Normally, attempts to deliver delayed mail happen at 63 regular intervals, the interval doubling after each failed 64 attempt. 65 66 Warning: flushing undeliverable mail frequently will result in 67 poor delivery performance of all other mail. 68 69 <b>reload</b> Re-read configuration files. Running processes terminate at 70 their earliest convenience. 71 72 <b>status</b> Indicate if the Postfix mail system is currently running. 73 74 <b>set-permissions</b> [<i>name</i>=<i>value ...</i>] 75 Set the ownership and permissions of Postfix related files and 76 directories, as specified in the <b>postfix-files</b> file. 77 78 Specify <i>name</i>=<i>value</i> to override and update specific <a href="postconf.5.html">main.cf</a> con- 79 figuration parameters. Use this, for example, to change the 80 <b><a href="postconf.5.html#mail_owner">mail_owner</a></b> or <b><a href="postconf.5.html#setgid_group">setgid_group</a></b> setting for an already installed 81 Postfix system. 82 83 This feature is available in Postfix 2.1 and later. With Post- 84 fix 2.0 and earlier, use "<b>$<a href="postconf.5.html#config_directory">config_directory</a>/post-install</b> 85 <b>set-permissions</b>". 86 87 <b>logrotate</b> 88 Rotate the logfile specified with $<a href="postconf.5.html#maillog_file">maillog_file</a>, by appending a 89 time-stamp suffix that is formatted according to $<a href="postconf.5.html#maillog_file_rotate_suffix">mail</a>- 90 <a href="postconf.5.html#maillog_file_rotate_suffix">log_file_rotate_suffix</a>, and by compressing the file with the 91 command specified with $<a href="postconf.5.html#maillog_file_compressor">maillog_file_compressor</a>. This will not 92 rotate /dev/* files. 93 94 This feature is available in Postfix 3.4 and later. 95 96 <b>tls</b> <i>subcommand</i> 97 Enable opportunistic TLS in the Postfix SMTP client or server, 98 and manage Postfix SMTP server TLS private keys and certifi- 99 cates. See <a href="postfix-tls.1.html">postfix-tls(1)</a> for documentation. 100 101 This feature is available in Postfix 3.1 and later. 102 103 <b>upgrade-configuration</b> [<i>name</i>=<i>value ...</i>] 104 Update the <a href="postconf.5.html"><b>main.cf</b></a> and <a href="master.5.html"><b>master.cf</b></a> files with information that 105 Postfix needs in order to run: add or update services, and add 106 or update configuration parameter settings. 107 108 Specify <i>name</i>=<i>value</i> to override and update specific <a href="postconf.5.html">main.cf</a> con- 109 figuration parameters. 110 111 This feature is available in Postfix 2.1 and later. With Post- 112 fix 2.0 and earlier, use "<b>$<a href="postconf.5.html#config_directory">config_directory</a>/post-install</b> 113 <b>upgrade-configuration</b>". 114 115 The following options are implemented: 116 117 <b>-c</b> <i>config</i><b>_</b><i>dir</i> 118 Read the <a href="postconf.5.html"><b>main.cf</b></a> and <a href="master.5.html"><b>master.cf</b></a> configuration files in the named 119 directory instead of the default configuration directory. Use 120 this to distinguish between multiple Postfix instances on the 121 same host. 122 123 With Postfix 2.6 and later, this option forces the <a href="postfix.1.html">postfix(1)</a> 124 command to operate on the specified Postfix instance only. This 125 behavior is inherited by <a href="postfix.1.html">postfix(1)</a> commands that run as a 126 descendant of the current process. 127 128 <b>-D</b> (with <b>postfix start</b> only) 129 Run each Postfix daemon under control of a debugger as specified 130 via the <b><a href="postconf.5.html#debugger_command">debugger_command</a></b> configuration parameter. 131 132 <b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b> 133 options make the software increasingly verbose. 134 135<b>ENVIRONMENT</b> 136 The <a href="postfix.1.html"><b>postfix</b>(1)</a> command exports the following environment variables 137 before executing the <b>postfix-script</b> file: 138 139 <b>MAIL_CONFIG</b> 140 This is set when the -c command-line option is present. 141 142 With Postfix 2.6 and later, this environment variable forces the 143 <a href="postfix.1.html">postfix(1)</a> command to operate on the specified Postfix instance 144 only. This behavior is inherited by <a href="postfix.1.html">postfix(1)</a> commands that 145 run as a descendant of the current process. 146 147 <b>MAIL_VERBOSE</b> 148 This is set when the -v command-line option is present. 149 150 <b>MAIL_DEBUG</b> 151 This is set when the -D command-line option is present. 152 153 When the internal logging service is enabled (by setting a non-empty 154 <a href="postconf.5.html#maillog_file">maillog_file</a> parameter value) the <a href="postfix.1.html">postfix(1)</a> command exports settings 155 that are used by child processes before they have processed <a href="postconf.5.html">main.cf</a> or 156 command-line settings. 157 158 <b>POSTLOG_SERVICE</b> 159 The name of the public postlog service endpoint. 160 161 <b>POSTLOG_HOSTNAME</b> 162 The hostname to prepend to internal logging. 163 164<b>CONFIGURATION PARAMETERS</b> 165 The following <a href="postconf.5.html"><b>main.cf</b></a> configuration parameters are exported as environ- 166
