If there's no DKIM, then there's not really any obvious domain to be
talking
about when it comes to reputation, so I don't think that's a question
that
makes sense (at least not without more details as to what you mean
by seeing a domain).
Also, I'm thinking in terms of points like for spammassin. Seeing
some patterns in the email increase or lower the points. I don't
think a whole reputation judgement would be done on DKIM alone,
Not all the time, no. But if the domain token attached to the message
via DKIM is on a whitelist, or if there's a significant positive
history,
then it's quite likely that the DKIM based reputation would override
other measures (and would likely be used to short circuit analysis
to avoid expensive content-based work).
unless the email is proven forged by DKIM but we are not there yet
as ADSP is not widely spread nor adopted.
Yup. That's probably out of scope for this discussion, anyway.
Cheers,
Steve
