whateveraddress@yahoo.com R=lookuphost T=remote_smtp defer (0): SMTP error from remote mail server after initial connection: host g.mx.mail.yahoo.com [206.190.53.191]: 421 4.7.0 [TS02] Messages from 216.104.33.122 temporarily deferred due to user complaints - 4.16.56.1; see http://postmaster.yahoo.com/421-ts02.html
I've gotten this too with some incoming mail, but I don't have yahoo. My ISP participates in this.
While most of what they reject is probably spam (based on what a friend says who provides DNS for a domain name of mine and forwards the email to me; many are "caught" by my ISP), I've had a couple completely legit private emails (not list mail) from friends get rejected too.
They tell me it isn't about user complaints about me. It's that they are matching the emails to a larger spam database. But it makes no sense to me since the legit emails that got rejected had no spam keywords and came from normal domains (one from yahoo).
Does anyone else have any experience with this, and is there something that I can do on my end that would help?
I can tell you it has nothing to do with Mailman.
