I just now changed HISTORY@PSUVM to use List-address= NJE, since our
default is FQDN.  See if this helps.  Eric sent out a note about
this type of problem a month ago.  In it, he said
 
"A serious problem exists when a peered list has a mix of 1.8 and 1.7 peers,
 and the 1.8 peers are configured to use Internet addresses ("List-Address=
 FQDN", or equivalent default)."
