On top of dreamhost dropping off the 'net just when I posted a bunch of screencasts... our socal-piggies meeting nearly got whacked because this month's organizer uses Yahoo, and most of the messages going through my mail server (which hosts the mailing list) were filed as "spam".
Now Yahoo is actively bouncing my e-mail.
... You can see for yourself that 220.127.116.11 isn't a known spam relay, isn't open, etc. It's just Yahoo looking at the volume of mail being sent and going "hey! wait a sec!" and listing me as a spam host.

This happened to us, and I don't know what to do about it. I also suspect that it was the mailing rate that triggered it. It was the default setting of postfix, but I guess Yahoo didn't like it. Nobody answers the mail or phone and I can't get it resolved.

Yahoo uses domain keys for verification and spf. Make sure you are using them or you email provider is.

I think the solution, extreme as it sounds, is some global law (no such thing, can't happen, I know) that finally brings a small charges for email, a penny or two for each email. It would largely wipe out spam, and thus: - Relieve the frustration that you described, since there would less (or none) incidences of mis-identifying spammers - Less time spent configuring spam filters and checking your junk mail box to see if your provider (gmail, yahoo, etc) inaccurately junked it. The only cons would be: putting some employeed programmers out of business who work on anti-spam software. And of course having to pay for the email, but if you don't regularly send mail, it could be less than 5 bucks a year
