Perhaps the best way would be if you tell us what (and how) you
understand these, before everyone here reads the postconf-parts to you
again...

You need "fast_flush_domains" if want to support ETRN, and or as
administrator you want to be able to run "postqueue -s adomain" for
specified (typically relay) domains.  In most cases (i.e. otherwise)
it is best to set "fast_flush_domains =" (empty).

You need "delay_warning_time = 2h" (or similar) if you want to generate
a notice to the sender when a message is delayed in your queue for (in
this example) 2 hours or more. At most one notice will be sent per message
before the message is either delivered or is bounced. In the latter case
a bounce notice is typically sent.

Enabling "delay_warning_time" has no effect on mail already in the queue,
the behaviour for each message depends on the value of the parameter at
the time the message entered queue.
