queue-priority in PowerMTA


Scope: domain
Type: number
Attributes: optional
Default: 50

When PowerMTA needs to deliver email for a queue but no connection slots are
available, it looks for a queue with lower priority currently connected and
interrupts as many connections as needed, starting with the lowest priority
connections and working its way up. A queue's priority is set with a number
between 0 (lowest) and 100 (highest); 50 by default.
