It looks like yahoodns.net has a NULL MX record, so anyone who emails to a
host there will not get far.
We saw these issues Thursday and Friday:
Site yahoo.com (98.136.216.26) said after data sent: 399 TCP Read
failed (Connection was closed. after 16 seconds) 16 sec"
The next most frequent message is:
Site yahoo.com (98.138.112.32) said in response to MAIL FROM (451
4.3.2 Internal error reading data)

I've seen others reporting this elsewhere too, so it's clearly a problem at
Yahoo's end.
Someone on the mailops list reported that disabling TLS for
yahoodns.net hosts fixed the problem so it may be worth trying that.
