Conceptually, MOTIS and Internet Mail provide very similar functionaility. SMTP + PEM + MIME + DNS MX Records and other useful internet services X.400 + ODIF or other + X.500 However, in practice, although there are probably as many seperate implementations of each, in terms of tried, tested, fielded and operational systems, the Internet is at least 3 orders of magnitude ahead of any other protocol suite - the only thing close in terms of installed base of protocols is Novell, which does not as far as I'm aware include a Mail System as part of its applcations, being a simple low level file sharing mecahanism with concommittend low level (1-4) protocols largely (albeit well designed and engineered!). [ i am excluding single organisation networkls like IBM or DEC or others internal systems as these have very few of the real world "Open System" problems to overcome ] as a site obliged to run X.400 (we wrote PP, after all, which is one of the best implementations), i prefer to use mime/smtp/pem of course, our system provides a single user interface, so i dont really have to know.... indeed a great portion of the x.400 mail around probleably travels by Internet anyhow.. jon
