Going way back, there were at least three implementations, two by two of the specification coauthors, developed in parallel with the MIME specification. Since then I've always tried to code in parallel with the specifications I'm involved with. None of this was in any way secret - in fact I've often stated that my position on such-and-such was the result of implementation experience - and I don't recall ever getting any flak for it. Hopefully this experience isn't unique to email protocols. Ned
