Ken Stone of HP-SDD sent me his copy of my recent note and the return
address is the strangest I've seen yet on this network...

The question is - how does one parse this?  There are a LOT of
ambiguities here ... including two '@' addresses and such.  It
seems to me that a decent return address would be parsable in
a unique fashion, rather than this "if the destination machine is
an ARPA gateway then it'll send to (?) hplabsd, if not, then if
it's a BITNET gateway it'll send to MIT-MC.ARPA (through an ARPA
gateway?) else it'll just send it to noscvax and let THEM deal
with it...

Anyone have any pearls of wisdom about all this?
