Thanks for the link. Server has been on this same IP Address for at
least 15 years. I've opened a ticket yesterday with Yahoo on that link,
I don't know how often it's monitored, I just submitted another one
asking for an update.
Of course, users are starting to notice that their emails are not going
through to yahoo since they're getting failed delivery notices, which
causes them to create test emails, which increases the number in the
queue waiting to be delivered to Yahoo....
T code is TSS04
67.195.228.106 15:44:56 Client session <<< 421 4.7.0 [TSS04] Messages
from 66.151.17.22 temporarily deferred due to unexpected volume or user
complaints - 4.16.55.1; see https://postmaster.yahooinc.com/error-codes
Thanks,

I assume there's a TS04 code in that error message. It is indeed
likely due to user complaints, but they have something of a hair
trigger for IPs not known to them. They ought to be able to get you
sorted out.
Assuming you have a limited number of DKIM domains in play, register
them all with the Yahoo feedback loop. Find info on that same website.
The Yahoo FBL is DKIM-based. It's meant for big bulk senders, but I
suspect it may give you a modest boost when it comes to reputation.
More importantly, you'll be able to see which goober is complaining
about legit mail. Assuming you're very low volume and not an ESP/CRM
platform, you're probably wondering where should FBL complaints go? In
my case, I just have them sent to an alias at my domain that for now
comes to me for manual review. With the intent that if it grows too
big to handle, I can redirect the alias to automation later. It works
fine; I get the occasional complaint about a jazz newsletter I send
out and I just manually unsubscribe anyone who complains.
Is this new? Yahoo does adjust filters regularly but overall this kind
of issue/process is not really anything new. This isn't futile; it's
easily fixable. It can just feel a bit overwhelming or unfair for
smaller or hobby senders.

I know it may be futile, but I thought I'd ask. Starting late Tuesday
afternoon, Yahoo has started deferring all email from my server. All
other internet domains are fine except for yahoo properties. There was
no increase of mail from my server that I can find. The only messages
in the outbound queue are waiting to be delivered to Yahoo, and are all
legitimate messages. And there's only about 160 of them. The Yahoo
error is just 'Messages from 66.151.xx.xx temporarily deferred due to
unexpected volume or user complaints' There was no increase in mail
volume on Tuesday before this error started.
All IPv4 traffic
SPF/DKIM seem to be functioning properly. I get the daily report from
Yahoo DMARC and it reports that the Server IP Address passes SPF/DKIM
Did Yahoo institute a new policy this week that I've missed setting up?
Thanks,
