Having read the list archives i'm aware of this one (:-), but with
Compuserve there's another 'Apparently-To'-problem, that causes all
recipients within Compuserve to appear in multiple Apparently-To headers (in
contrast to the list name apprearing in a single Apparently-To header with
the 'classical' problem).
It seems that theese multiple headers are generated by the Compuserve MTA if
it finds an invalid address in the To:-header. Therefore the (not very
extensively tested) is to put a valid Compuserve address in the To:-header -
which may look quite odd sometimes...
