FYI- I tried to sign up with Yahoo for their feedback loop system but they said this:
"Senders who wish to participate in the Complaint Feedback Loop program are required to sign their outbound email with DomainKeys and/or DKIM, both of which are email authentication technologies that Yahoo! Mail utilizes to determine the actual sender of an email. (We do not offer feedback loops based on a sender's IP addresses or CIDR ranges.)"
Then they also said this:
"If you have yet to utilize domain-based email authentication, we encourage you to consider DKIM, which is the successor to DomainKeys."
