...Maybe next time this happens I will take them up on their offer of an "appeal" address to which to forward the message ...
Hey, that's a useful provision (they actually tell you they've stopped a specific piece of mail?). As I've moaned 'here' before, my ISP uses outgoing filtering too, but just silently drops anything it catches and makes no offer to 'whitelist' the likes of SC submit addresses. Not that I get enough spam for it to be an issue these days. Anyway, your provider's 'appeal' process, if it actually works, seems like a good one. Otherwise, all these disparate anti-spam initiatives tend to be pulling in different directions.
