Create a softer minimum poll restriction.  Allows *poppollpadding*
connections before the minpoll restriction is triggered.  Additionally, one
padding entry is recovered every *popminpoll* minutes.  This allows for the
occasional polling rate faster than popminpoll, (i.e., for clients that
require a send/receive to send mail) but still enforces the rate long-term.
Default is 1 (disabled).

The easiest way to think of it is a queue of past connections, with one
slot being filled for every connection, and one slot being cleared every
*popminpoll* minutes. When the queue is full, the user will not be able to
check mail again until a slot is cleared.  If the user waits a sufficient
amount of time, they will get back many or all of the slots.
