I used to maintain one but now I point folks at the Validity universal FBL signup page. Last I looked they were also including FBLs that they didn’t handle the signup for. A few things to note: * all the FBLs that I am aware of include consumer mail, even when the mailbox provider handles mail for hosted domains * with the exception of Google’s complaint percentage calculation in postmaster tools, FBL %s may not reflect actual complaint percentages. In most places recipients cannot report spam for mail already in the spam folder. * FBL reports typically are only generated when the recipient is using a client provided by the FBL provider. If someone is using Outlook for desktop or Apple’s mail.app the “this is spam” button does not generate a FBL complaint. * it is common (and has been for a decade or more) for bad players to manipulate complaint percentages through waterfalling another other techniques as a way to hide their activities from abuse desks. * from my perspective, complaint rates are an increasingly unreliable signal. a very high complaint rate is informative, but the a lot of spam goes to the bulk folder and gets few or zero complaints. laura -- The Delivery Experts Laura Atkins Word to the Wise [email protected] Email Delivery Blog: http://wordtothewise.com/blog
