No, but working for an ESP myself, I can tell you that the end users often do complain about non-receipt of email, and I am sure I am not the only person who has nudged a user to switch ISPs (or webmails) because of a poor choice of spam filtering and deafness of their previous ISP. It does happen. It's true that Joe User doesn't know about the DNSBL's involvement, and may not even know what a DNSBL is. But, being the guy at this ESP who works with ISPs and blacklists, and there have to be a lot more people like me out there. Both fixing things to prevent or address listings from DNSBLs that can be worked with, and by helping ISPs to understand when a stupid blacklist should be called a stupid blacklist and ignored. (Just for the record, the only instances in which my point of view actually aligns with Dean Anderson's point of view are purely coincidental. Call it the stopped clock principle.) > In the end, walking isn't a viable alternative. Because it's so hard to open a Gmail account? I think your thinking here is about two generations out of date. Back in 1995 when we each had our one dialup account, and webmail was much less common and acceptable, your point would have been more valid.
