The _ is not allowed in hostnames, but MS Exchange replaces whitespace
with _ in hostnames, when it sends HELO.
The 'solution' is to set
helo_allow_chars = _
in your exim config, if you want to receive mails from such broken
mailers. Btw, AFAIK, it's impossible/not easy to change the hostname on
a windows-server, so don't expect the sending side to fix it ;)
