I guess I've never really seen the point of publishing a SPF record if
it ends in ~all.  What are people supposed to do with that info?

Get your mail delivered to Hotmail, the last significant outpost of
SPF/Sender-ID.  Other than that, I agree it's useless.

I also agree that any domain with live users (as opposed to mail
cannons sending ads or transaction confirmations) is likely to
experience pain with -all from all the overenthusiastic little MTAs
whose managers imagine that "stopping forgery" will lessen their spam
load rather than losing mail from roaming users.


In all fairness, the roaming users problem isn't a problem when one uses smtp auth and a constant submission point.
