No idea how long ago, but it looks like at least at some point there was a way to do that. I recovered the account and tried to delete it, don't recall how it went. That address also receives a bunch of other mail for this person who thinks it's their email address, like from their church listserv. No idea if they just don't know their address or it's a common typo or misreading. I just delete it and move on. This type of thing is depressingly common for addresses that are common names and such at the major providers. One of the early folks at RocketMail had d...@yahoo.com and it was nearly impossible to use because of the amount of misdirected mail. For Gmail's launch, we required longer logins and banned something like the 5000 most common names we could find and also prevented any simple homoglyphs, and still folks end up in this state. Detecting misdirected mail is a lot harder than regular spam, if not impossible. It's mostly one-off messages like receipts where COI isn't expected. It'll also catch various manual lists that otherwise get away without COI (ie, despite it being a best practice, if the complaint rate is low enough because the number of addresses added is low enough and they're usually the correct address and usually manual adds)... or it'll be things like one to one messages like someone who gives their email address to a car salesman when they do a test drive. You can treat these all as spam, and as misdirected mail, they are. The problem is, they aren't usually of a volume that matters and using them to block the source is likely to have more false positives than not. Even on a single user basis, knowing that one receipt from randomebiz.com is spam and when that user actually buys something there it isn't... good luck. Frankly, there aren't really any great solutions. Luckily, most users don't get much of this if any. Brandon
