OK - this might sound really ridiculous, and I'm dying to be proven wrong - but based on my experience this week, if you send ONE SINGLE e-mail to a Yahoo! Mail user and it gets too high of a "bad word" score - then, foreverafter, all e-mails from your mail server's IP address will default to delivery in their spam folder (yahoo's MTA will add the "X-YahooFilteredBulk" header to each inbound message). If you, by some total happenstance, discover this (wondering why your Yahoo friends were ignoring you) and wish it undone, you must fill out a massive 20+ item questionnaire about your privacy & opt-out policies, submit hyperlinks to your unsubscribe forms and policy pages, etc. If, however, you are not *actually* a bulk mail sender (for example, you run a private server just for you and a few friends/colleagues) and thus have no such things, you're fucked - they will not unflag the server IP - and they don't care. They just suggest that you "teach" your contacts how to remove your e-mail from the spam folder. They also have really, really, really shitty reading skills (as in, they don't actually read your responses to their e-mails, and just keep asking the same irrelevant questions as if they are not human.) And they have strange movie names like "Eddie" and "Hank" so perhaps they aren't. - Anthony Citrano

Their latest response: "Based on the information you have provided us, we cannot systematically deliver your email to the Inbox at this time." Well alrighty, then! - Anthony Citrano
