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,
