In the US, they aren't under legal obligation to do so, which seems to vary from some laws elsewhere.

However, if the ESP is claiming to be white-hat and only send mail where permission exists, one would think that they would share it freely and include a clause in their customer terms and conditions that their customer's identity would be released to a recipient on request.

Scenario 1:

Victim to ESP: I got this spam from your IP and have no idea why. It touts some product, but all of the links are tracking bugs that point back to you. Where did you get my address and on whose behalf did you send it?

ESP to victim: None of your business, but our customer said that they have your permission and we trust them more than we trust you. Besides, they are the one paying us and you're not. Shut up and eat your spam.

Victim to ESP: Well I don't think they do have permission, and I'd like to ask them to stop contacting me. Seeing as you've hidden the actual sender via tracked links that just point back to you, I have no way of verifying if it's legitimate.

ESP to victim: We're not telling. So sue me. If you ask really nicely we'll listwash you, but just for this one customer and we're not telling you who it is.

Scenario 2:

Victim to ESP: I got this spam from your IP and have no idea why. It touts some product, but all of the links are tracking bugs that point back to you. Where did you get my address and on whose behalf did you send it?

ESP to victim: That mail was sent on behalf of ABC Company, and you can contact them [here]. We don't tolerate spammers, and our customer contracts require openness so these issues can be resolved. Attached is a PDF of their signed statement where they certify that they have your permission and agree that we may release their identity on demand.

Why would a legitimate ESP insist on hiding the identity of its customers from their victims? Isn't the point of bona-fide permission-based bulk mail to build that relationship with the ESP a transparent background entity? What legitimate company sends bulk permission-based mail anonymously?

IMNSHO, if you send bulk promotional mail, and it generates complaints, and you shield the identity of the sender from the recipient, you aren't an ESP. You're a spammer-for-hire.
