many yahoo users on my Mail Queue

 From time to time I have mail to yahoo.com delayed (and to
rogers.com, 
a large Canadian ISP who outsources mail to yahoo).

I looked over their "postmaster webpages" where
they claim that they do 
NOT use graylisting, but whatever they are doing sure
behaves like 
graylisting. The mail is never refused, just delayed.

They also have a support form you can fill out to request
help on 
finding out why your mail is delayed. Miraculously, whenever
I fill it 
out (twice now) I never get any response, but the
graylisting behaviour 
stops.

I filled it out once last year in September or November, but
come 
January, their
"do-something-that-looks-like-graylisting-to-this-guy&q
uot; 
flag must have been reset.

I have proper SPF records in place - but not Domain Keys.
They might be 
more forgiving if you used Domain Keys.

The prtc.net warning looks like they count mail from your
server and 
enforce some kind of DNS rule if you exceed a quota. It is a
452 error 
which means the mail should just be queued for a while and
then go 
through. I would send an email to postmasterprtc.net
and ask why they 
are throttling legitimate mail to their users.

A search for "yahoo postmaster" on Yahoo gives
this as the first hit:

> h
ttp://help.yahoo.com/help/us/mail/defer/index.html

It has a series of questions and answer links. You should
read a few to 
make sure they don't apply to you.

The form is at:

> http
://add.yahoo.com/fast/help/us/mail/cgi_defer

But read the suggestions they make here first:

Where do they locate this page as I do notice rogers.com
delaying  
forwarded email.

I use Domainkeys but I'm not sure if it actually applies in
forwarded  
mail case. Certainly my local application has not helped.
