But then we have the whole excessive DNS traffic problem again.
I haven't seen anyone present convincing evidence of "excessive DNS
traffic" when MX mechanisms are checked. Won't DNS caching will
completely eliminate any potential problem?
In fact I have heard (admittedly, not seen) evidence to the contrary,
namely that even the large ISPs receive the vast majority of their e-mail
from only a few domains. It follows that the DNS impact would quite
possibly not be as severe as we all assume.
Published empirical evidence would be great and would definitely cut down
on the room for rhetoric.
