[Mimedefang] Mildly Off-Topic: Yahoo! Mail

I am becoming increasingly frustrated with Yahoo! Mail.

A large majority of our mail to Yahoo! is being deferred akin to greylisting 
practices.  That I can live with.  But even after the deferment is done and 
the mail is delivered from our side, Yahoo! users are complaining the email 
is never received.  And these users are familiar with checking bulk mail / 
spam folders for false positives.

Filling out their forms seems to be a waste of time because our servers are 
"shared" servers that host multiple domains, legitimate mailing lists, etc.

Of course, we are white-hats, don't send/allow UCE, have full smtp auth and 
anti-viral/spam policies.

We also allow mail forwarding and we only tag, not block SPAM.  We are also 
the backup MX for hundreds of people.  This means that despite even best 
internet practices, we do send DSNs, we do relay "spam" (marked as such), 
etc.

Anyway, so short of telling people we will no longer perform backup MX, not 
allowing mail forwarding or changing our fundamental policy on tagging spam 
and avoiding false, positives, I'm looking for answers.

The first suggestion many people have made is to get domainkeys working. 
However, most of that work in MD doesn't seem to be functioning according to 
the wiki entry.  Anyone have it working?

Or better yet, does anyone have any comments or contacts at Yahoo! in their 
postmaster division?  It's getting to the point where the only thing I can 
do is recommend people don't use Yahoo! mail and it's a wonderful interface 
that has long supported groups including many non-profits I care strongly 
about.

Regards,
KAM
