   [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

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.
