Please consider how many MTAs interact on the global Internet. Please
consider that each is operated by a different, independent organization.
Please consider that there is no single authority over all those
A flag day is not possible for changing the infrastructure of any
network operation that is large. Even when there is a single authority,
service operators cannot perform a conversion "instantly".
In a medium-sized company -- and that means that theoretically there is
a single authority over everyone -- a serious change to the network
infrastructure will take at least 6 months.
For the Internet, it takes many years to obtain broad adoption of a
ps. Please note that there is still no large-scale use of certificates,
although the technology for them has existed for years. Therefore it is
important to be very conservative, when specifying a system behavior
that depends upon their use.
