<b>NAME</b>
|
|
qmqpd - Postfix QMQP server
|
|
|
|
<b>SYNOPSIS</b>
|
|
<b>qmqpd</b> [generic Postfix daemon options]
|
|
|
|
<b>DESCRIPTION</b>
|
|
The Postfix QMQP server receives one message per connec-
|
|
tion. Each message is piped through the <a href="cleanup.8.html"><b>cleanup</b>(8)</a> dae-
|
|
mon, and is placed into the <b>incoming</b> queue as one single
|
|
queue file. The program expects to be run from the <a href="master.8.html"><b>mas-</b></a>
|
|
<a href="master.8.html"><b>ter</b>(8)</a> process manager.
|
|
|
|
The QMQP server implements one access policy: only explic-
|
|
itly authorized client hosts are allowed to use the ser-
|
|
vice.
|
|
|
|
<b>SECURITY</b>
|
|
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.
|
|
|
|
<b>DIAGNOSTICS</b>
|
|
Problems and transactions are logged to <b>syslogd</b>(8).
|
|
|
|
<b>BUGS</b>
|
|
The QMQP protocol provides only one server reply per mes-
|
|
sage 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.
|
|
|
|
<b>CONFIGURATION</b> <b>PARAMETERS</b>

|
The following <b>main.cf</b> parameters are especially relevant
|
|
to this program. See the Postfix <b>main.cf</b> file for syntax

details and for default values. Use the <b>postfix</b> <b>reload</b>
|
|
command after a configuration change.
