the latter (controllable by email address) is not correct as i 
understand things, either the domain has a set of legal sending hosts or 
it doesn't ...

I think the problem is that there are those touting it as a anti-spam 
measure, when it clearly is not and that admins are making decisions 
about what recipients of emails from their domain may do with regard to 
forwarding and that they mostly don't understand the implications ...

you don't forward your email, but others receive your email *may* want 
to forward it and if you have an SPF record and they use a provider with 
strict checking, they may not be able to do that ...

it is perfectly legitimate behaviour for me to forward my gmail account 
email to some other host, but SPF checking may cause that email to be 
rejected by that other host because the *original sending* host has very 
strict definitions of where its mail can originate from ...

i realize that some of you have already made up your mind and that's 
fine by me, others may not have done so and may benefit from this 
discussion ...
