RE: AD review comments on

In fax, it's impossible to determine if the user has walked to the
fax machine and picked up (retrieved) the paper facsimile.  In 
fax, the message is considered "retrievable" when the sender 
completes transmission of the fax.

I don't understand the need to do more with fax-over-SMTP:  if
the message is "retrievable", you're already duplicating what
fax on PSTN does today.


That said, timely delivery is all good stuff, but I don't
see a need to redefine "delivery".
