When the original RFCs were written *every* Internet host had a static
IP. It was taken for granted. That was the way the Internet worked. But
there was no DNS...
The newer RFCs don't mention this either (I suspect - I haven't read
every RFC). However, in practice, you will find it very hard to run an
MTA reliably without a static IP and reverse DNS. That's just the way it
is.
