THAT to me may be the real experiment here. yes indeed ... to do this correctly it's necessary to record details of all previously received messages (whether or not they contain the new feature) if one is to correctly place a newly arrived message (which has the feature) into the correct place in the sequence before deciding whether or not the UI needs to be invoked I suspect many implementations will not bother... so why specify something that is most likely going to be ignored ?? ... now I've never studied how often sequences of email messages are shuffled out of their sending order before delivery, but queuing mechanisms in MTAs tend to speculatively try to deliver each new message and then, if that succeeds, deal with any backlog. Clearly ??? it is not the intent of this document to affect design decisions here. - -- richard Richard Clayton Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
