Consider what I believe Y! does in their MUA: if it's got a valid signature
from isp.com with a From: [EMAIL PROTECTED], it doesn't get a nice little
message saying that Y! believe it came from customer.com. Thus the
outsourced mail will not be treated on a par with mail signed on behalf of
the domain.
It makes sense that customer.com would publish an SSP record saying "my mail
is all signed by isp.com".
But I still don't see what benefit it is for isp.com to say "we sign some
other people's mail." If isp.com signs other people's mail, we'll know
because we'll see the signatures.
The statement that I sign only my own mail makes perfect sense.
