You should not be surprised. :-)

The problem is the "_" character in the HELO/EHLO argument; it is not
legal. By default Exim will not accept it.

However, if you search the mailing list archives you will see the
discussions related to this, and the instructions for how to accept it.
It is your choice whether to do so or not; given the high number of
misconfigured Microsoft Exchange servers out there (and the ridiculous
difficulty of renaming them), you will probably end up accepting them.
