I don't think that's the case for most spam these days. For a
spambotnet of compromised home systems, you'll see:
Spambot A => Recipient Server C => (Bounce) => Forged Email Server D
I think you've just proved my point. It's too hard to try and
determine who to contact in these situations
I already use SPF HARDFAIL, so I could ALSO complain to Recipient
Server C about NOT using SPF to reject the email from SMTP Server
B.
Agreed.
Again, this has merit but your approach will determine how successful
you are. Also, it may be easier to determine who to approach about
the subject.
