That number BF683A28247 is a unique number?
The postfix queueid identifies a single message while it's in
the queue. The queueid is created from the queue file inode
number and microsecond CPU time.
The queueid is unique while that message exists; only one
message at a time may have a specific queueid.
Once the message exits the queue, that queueid can be reused
at any time.
I've seen a queueid reused within 30 minutes. Don't count on
it being unique for any period of time.
