Doubt that your type of account has anything to do with your inability to 
reply.  I wouldn't be able to reply from my Vax account either.  

Seems like the sending machine or possibly a gateway machine between the 
mail's origin and your location is broken, failing to put a recognizable 
address on mail which it passes.  Seems like it might be easier to 
determine where the problem is and advise you on how to circumvent it if 
you were able to produce a full set of headers.  Just the address by itself 
is pretty vague.
