Here is another v=spf1/PRA incompatibility scenario I ran across today with

Return-Path: <localpart(_at_)mobileemail(_dot_)vodafone(_dot_)net>

Reply-To: username(_at_)example(_dot_)com
From: "John Doe" < username(_at_)example(_dot_)com>
Apparently Vodafone (in the UK) use their own return path for Blackberry
e-mails. This would be no problem for SPF, but creates a case where the PRA
and Mail From records for example.com need to be different.
Since Vodafone doesn't publish an SPF record, I'm really not sure what to
tell
this person to do. I'm thinking it may have to be the PRA opt-out record.
...which would not work for hotmail.
But adding "Sender: someone(_at_)example(_dot_)com" (and I mean this literally!)
would probably work as example.com does not have an SPF record so the
PRA would be fooled.
Hmmm...
Perhaps "Sender: localpart(_at_)mobileemail(_dot_)vodafone(_dot_)net" is less
risky.
