How is the queue ID determined? Completely randomly, or does Postfix
try to avoid re-using an queue ID too quickly?
This is a postfix internal function, and is intentionally
undocumented because it may change with future releases.
Search the archives if you really want to know.
I'm curious about this because I've never seen Postfix re-use a queue ID
quickly at all, where with qmail I see this all the time.
The important point is that postfix guarantees a QUEUEID will
be unique within the current queue. As soon as that file is
released, that same id can be reused any time.
I've seen postfix reuse a QUEUEID within just a few minutes.
