The program expects to be run from the +\fBmaster\fR(8) process manager. + +The QMQP server implements one access policy: only explicitly +authorized client hosts are allowed to use the service. +.SH "SECURITY" +.na +.nf +.ad +.fi +The QMQP server is moderately security\-sensitive. It talks to QMQP +clients and to DNS servers on the network. The QMQP server can be +run chrooted at fixed low privilege. +.SH DIAGNOSTICS +.ad +.fi +Problems and transactions are logged to \fBsyslogd\fR(8) +or \fBpostlogd\fR(8). +.SH BUGS +.ad +.fi +The QMQP protocol provides only one server reply per message +delivery. It is therefore not possible to reject individual +recipients. + +The QMQP protocol requires the server to receive the entire +message before replying. If a message is malformed, or if any +netstring component is longer than acceptable, Postfix replies +immediately and closes the connection. It is left up to the +client to handle the situation. +.SH "CONFIGURATION PARAMETERS" +.na +.nf +.ad +.fi +Changes to \fBmain.cf\fR are picked up automatically, as \fBqmqpd\fR(8) +processes run for only a limited amount of time. Use the command +"\fBpostfix reload\fR" to speed up a change. + +The text below provides only a parameter summary. See +\fBpostconf\fR(5) for more details including examples. +.SH "CONTENT INSPECTION CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBcontent_filter (empty)\fR" +After the message is queued, send the entire message to the +specified \fItransport:destination\fR. +.IP "\fBreceive_override_options (empty)\fR" +Enable or disable recipient validation, built\-in content +filtering, or address mapping. +.SH "SMTPUTF8 CONTROLS" +.na +.nf +.ad +.fi +Preliminary SMTPUTF8 support is introduced with Postfix 3.0. +.IP "\fBsmtputf8_enable (yes)\fR" +Enable preliminary SMTPUTF8 support for the protocols described +in RFC 6531..6533. +.IP "\fBsmtputf8_autodetect_classes (sendmail, verify)\fR" +Detect that a message requires SMTPUTF8 support for the specified +mail origin classes. +.PP +Available in Postfix version 3.2 and later: +.IP "\fBenable_idna2003_compatibility (no)\fR" +Enable 'transitional' compatibility between IDNA2003 and IDNA2008, +when converting UTF\-8 domain names to/from the ASCII form that is +used for DNS lookups. +.SH "RESOURCE AND RATE CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBline_length_limit (2048)\fR" +Upon input, long lines are chopped up into pieces of at most +this length; upon delivery, long lines are reconstructed. +.IP "\fBhopcount_limit (50)\fR" +The maximal number of Received: message headers that is allowed +in the primary message headers. +.IP "\fBmessage_size_limit (10240000)\fR" +The maximal size in bytes of a message, including envelope information. +.IP "\fBqmqpd_timeout (300s)\fR" +The time limit for sending or receiving information over the network. +.SH "TROUBLE SHOOTING CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBdebug_peer_level (2)\fR" +The increment in verbose logging level when a nexthop destination, +remote client or server name or network address matches a pattern +given with the debug_peer_list parameter. +.IP "\fBdebug_peer_list (empty)\fR" +Optional list of nexthop destination, remote client or server +name or network address patterns that, if matched, cause the verbose +logging level to increase by the amount specified in $debug_peer_level. +.IP "\fBsoft_bounce (no)\fR" +Safety net to keep mail queued that would otherwise be returned to +the sender. +.SH "TARPIT CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBqmqpd_error_delay (1s)\fR" +How long the Postfix QMQP server will pause before sending a negative +reply to the remote QMQP client. +.SH "MISCELLANEOUS CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBconfig_directory (see 'postconf -d' output)\fR" +The default location of the Postfix main.cf and master.cf +configuration files. +.IP "\fBdaemon_timeout (18000s)\fR" +How much time a Postfix daemon process may take to handle a +request before it is terminated by a built\-in watchdog timer. +.IP "\fBipc_timeout (3600s)\fR" +The time limit for sending or receiving information over an internal +communication channel. +.IP "\fBmax_idle (100s)\fR" +The maximum amount of time that an idle Postfix daemon process waits +for an incoming connection before terminating voluntarily. +.IP "\fBmax_use (100)\fR" +The maximal number of incoming connections that a Postfix daemon +process will service before terminating voluntarily. +.IP "\fBprocess_id (read\-only)\fR" +The process ID of a Postfix command or daemon process. +.IP "\fBprocess_name (read\-only)\fR" +The process name of a Postfix command or daemon process. +.IP "\fBqmqpd_authorized_clients (empty)\fR" +What remote QMQP clients are allowed to connect to the Postfix QMQP +server port. +.IP "\fBqueue_directory (see 'postconf -d' output)\fR" +The location of the Postfix top\-level queue directory. +.IP "\fBsyslog_facility (mail)\fR" +The syslog facility of Postfix logging. +.IP "\fBsyslog_name (see 'postconf -d' output)\fR" +A prefix that is prepended to the process name in syslog +records, so that, for example, "smtpd" becomes "prefix/smtpd". +.IP "\fBverp_delimiter_filter (\-=+)\fR" +The characters Postfix accepts as VERP delimiter characters on the +Postfix \fBsendmail\fR(1) command line and in SMTP commands. +.PP +Available in Postfix version 2.5 and later: +.IP "\fBqmqpd_client_port_logging (no)\fR" +Enable logging of the remote QMQP client port in addition to +the hostname and IP address. +.PP +Available in Postfix 3.3 and later: +.IP "\fBservice_name (read\-only)\fR" +The master.cf service name of a Postfix daemon process. +.SH "SEE ALSO" +.na +.nf +http://cr.yp.to/proto/qmqp.html, QMQP protocol +cleanup(8), message canonicalization +master(8), process manager +postlogd(8), Postfix logging +syslogd(8), system logging +.SH "README FILES" +.na +.nf +.ad +.fi +Use "\fBpostconf readme_directory\fR" or +"\fBpostconf html_directory\fR" to locate this information. +.na +.nf +QMQP_README, Postfix ezmlm\-idx howto. +.SH "LICENSE" +.na +.nf +.ad +.fi +The Secure Mailer license must be distributed with this software. +.SH HISTORY +.ad +.fi +.ad +.fi +The qmqpd service was introduced with Postfix version 1.1. +.SH "AUTHOR(S)" +.na +.nf +Wietse Venema +IBM T.J.
