Yahoo also keeps track of sender reputation, on a per IP basis.  Once
one of your IPs has a reputation that's below average, it takes a lot
of time before it works its way back up to a good status.  They won't
tell you what your status is, hell, it's hard to get anybody to email
you back in less than 24 hours, but they do get back to you
eventually.  In general, it sounds like their postmaster group is
overworked and they're just struggling to keep up with the load.

We've got IP's that we've been sending from for years and have never
had problems with. We rolled out a system last year with some new IP's
and as long as volume was low, there were no problems.  But as we
added users, and they registered domains, and they forwarded their
email to their yahoo mailboxes, we started getting blocked.

Another thing to consider is that you should segregate your sending
IP's in some manner similar to the following:
1) SMTP Authenticated traffic (dk and/or dkim signing here would be a
positive thing).
2) Webmail traffic (dk and/or dkim signing here is good too).
3) Forwarders (do not dk mor dkim sign here).
4) Locally generated traffic (dk and/or dkim signing here too).

All truth passes through three stages. First, it is ridiculed. Second,
it is violently opposed. Third, it is accepted as being self-evident.
