No, what will happen more and more is that parties who forward email will have to make a "best effort" to ensure that it is not spam.
Meaning a policy "unfiltered email does not get fowarded to external parties"
This was my point. Have we already come to the day where regular e-mail forwarding is no longer workable? If so, we'll adapt, naturally, but I didn't think that day had come yet. And I didn't think Bellsouth would be leading the way.
This is a problem. Headers would go a long way to disabling the forwarding instances and/or mandating strict filtering for those customers.
That being said, assuming you have told bellsouth you were working on eliminating raw forwarding they should have worked immediately to lift the block and give you the benefit of the doubt.
Bellsouth hasn't even said they want forwarding eliminated or filtered; they are just being obstinate and unhelpful. Kevin
