On that note, wouldn't that just 'move the problem'? If we waved our
magic wands and made all e-mail require SPF, DKIM, and DMARC or it goes
to junk, a mail server compromise would lead to a bunch of spam that was
SPF-allowed, DKIM-signed, and DMARC-policy-acceptable. And we'd still
have spam in our inbox. ;)
Spammers were often the first ones using those :)
As a matter of fact, there are some spammer specific filtering rules
that use that as an identifier already :)
All it really does is stop accepting legitimate email that has been
forwarded on to destination (SPF fail).. but again, remote forwarding
should go the way of the dodo..
And remember, SPF/DKIM/DMARC are NOT used for spam identification, it is
used for a very different purpose. (Verifying/Confirming Source)
The fact that forgeries are often spam, is simply a by product..
