Possibly. What's the problem you're trying to solve?
I really hate it when people ask pragmatic questions like that. I
mean, really Steve, didn't you know that value propositions are
soooo pasé?
But I suppose I have to answer it:
I'm about to generate a bounce-category message. If I'm suspicious
enough of the original message, I might decide not to. By way of
trying to squelch bad bounce traffic at its source.
Given the DKIM sig and the "Return" SSP record, I'll generate it
since the return address domain has said it's valid.
Wouldn't you be better looking at the i= tag in the DKIM-Signature
header, anyway?
Cheers,
Steve
