The "Unexpected connection response from server:" is not limited to Yahoo accounts

Thank you

The part between "

server:" and "

follows."  is blank.

Is there anything else to look at to try to get an idea of the reason for the bounce? There is nothing interesting in the header:

We're trying to figure out whether it is a bad address that should be removed, unable to connect and retry later, etc. But no status codes on these (other messages have them but many do not).

Any suggestions?

THANKS !
