The whole point of Spam Arrest - automated systems cannot self-authorize their sent emails, and that's fine with me. I send stuff by Fedex online, receive order confirmations from Amazon and B&H, get credit card statements, and subscribe to few legit mailing lists and Yahoo groups (not to mention GG). I never miss them because they're all smart enough to send their email from the same email address over and over, and once you approve each sender you get whatever they send. What you are missing is that you - the recipient - can approve the email sender from a list of pending (or "unverified") emails, you don't have to depend on the sender to do it. Yes, you have to approve them the first time because the humans on the sender side can't, but so what? That's why your suspect email is held - on Spamarrest's site for a week or so - in an "unverified" box, and I check that at my leisure, usually a couple times of day. As I said, I re-sort the suspect email based on the subject line, and you'd be amazed at how easily legitimate email shines through. You can also "whitelist" or "blacklist" entire domains.
Yes, in a perfect world there would be a "solution" to spam. When you have one let me know, until then I'll stick to spam arrest.
