3 qmail-qmqpc \- queue a mail message via QMQP
8 offers the same interface as
10 but it gives the message to a QMQP server
11 instead of storing it locally.
17 is replaced with a symbolic link to
22 IP addresses of QMQP servers, one address per line.
24 will try each address in turn until it establishes a QMQP connection
25 or runs out of addresses.
