Is your incoming MTA greylisting? This can cause delays and out of
sequence messages, and you can't control the delay because it's
entirely up to the sending MTA. However, if it is greylisting, it
would normally affect only the first post from any particular user to
any particular list. Also, if the message reaches the list archive
without delay, that rules out greylisting.

OK if the problem is only delay and not totally missing messages,
however, it is possible that some AOL (or other ISP) users will
receive a message and others not because of their individual
whitelists, spam options, etc.

This sounds like a backlogged out/ queue --

OK, so the out/ queue is not backlogged all the time, but maybe it is
sometimes. Maybe it's not at all in which case the delays are in
outbound Postfix or beyond.
