Sadly that must have been during my failed attempt of converting to b4 prep / b4 send before sending this last Friday and then it got lost. It almost worked and is a very nice work flow except that b4 currently can only use a single list of To/Cc fields and for this treewide series that would probably hit mail server limits. Added it now. Thanks, Niklas
