It appears that AOL is blocking one of our lists from distribution to their

Sure, one can try to get AOL to change.  However, we chose to deal with the
problem differently when it became apparent that many of our AOL
subscribers were not getting our messages.  We contacted LSoft and they
stated that they knew of the problems.  The suggested that we add a
"Mail-Via= Direct" to our lists (all 800!) to bypass use of the LISTSERV
backbone (an obsolete architecture?) which would reduce the likelihood of
AOL considering our messages spam.  LSoft also suggested setting up a
specific SMTP route in LSMTP for AOL with relatively low number of
recipients and connections.  These actions solved our problems.  However,
we were disappointed that LSoft did not proactively mention the problem and
its solution to its customers.

I hope you find this information useful.
