Do you see AOL or Earthlink, which both have SPF records, actively
preparing their users for SMTP authentication?
Have you done any estimates on how much $$$$ it might cost Earthlink to
upgrade it's *millions* users?
Has any cost analysis at all been done on SPF "-all"????????
No cost analysis from me. I'm just a small ISP. For AOL its easy: AOL
10.0 Earthlink would be similar. They spend millions littering mailboxes
and TV screens nationwide, maybe even worldwide with advertisements and
CDs. Either one is capable of painless user upgrades to ease the
transition. In fact, it would help push their portal services to move
off-network customers to their browser based mail client.
Remember that publishing SPF records does not help the publisher. Most
people have a problem with receiving forgery, not sending it.
I'll agree that publishing does have a direct effect on recipients, but
there is also a great benefit in protecting the reputation of forged
domains.
