qmqpd [generic Postfix daemon options]

The QMQP server implements one access policy: only explicitly authorized client hosts are allowed to use the service.  

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.  

The text below provides only a parameter summary. See postconf(5) for more details including examples.

receive_override_options (empty)

The increment in verbose logging level when a remote client or server matches a pattern in the debug_peer_list parameter.

debug_peer_list (empty)

Optional list of remote client or server hostname or network address patterns that cause the verbose logging level to increase by the amount specified in $debug_peer_level.

ipc_timeout (3600s)

The time limit for sending or receiving information over an internal communication channel.

max_idle (100s)
