While doing a little searching, I found some information on email feedback loops for other major ISP’s.
- Road Runner
- AOL (don’t bother, see note 1)
- Rackspace (don’t bother, see note 1)
- Earthlink – Send an email at email@example.com and provide your IP range, domains, contact information, and the email address for sending complaints.
- Outblaze – Send an email with a feedback loop request at firstname.lastname@example.org
Interestingly enough, most of them use Return Path for FBL services.
Note 1: AOL and Rackspace’s feedback loop’s are completely useless … as they don’t tell you who’s complaining … just that a complaint is made. Kind of hard to fix a problem if you don’t know who’s reporting the problem.
