is rumored to have said:
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.
I've seen that happen as a result of relatively small and slow spam runs
via compromised accounts. Only Yahoo/Oath notices.
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,
Nate Burke
