Is the >X400 protocol inherently more dependable than the present method? >Mary Theoretically X.400 is more reliable yes. But then again betamax was theoretically better than VHS (sorry to trot out my old chestnut analogy again !). IMHO it comes down to whether you are willing to put up with second best (SMTP mail) but accept it's cheap and readily available and everyone uses it and it works pretty well, or want the best (X.400) but accept it's expensive with not many products available. If SMTP wasn't very good, then gp-uk wouldn't work very well, would it? Hoping the message arrives...but without the time to plough through an audit trail if it doesn't (I'll just send it again)....
