It's not you (running Exim) who has the problem with RFC's, it's the
Windows boxes. *Your problem* will be if your site misses important mail
from users *behind* that brain-dead windows admin who setup the windows
box. And if it's an email to the boss of your company (if your Exim box is
gateway for corporate site) it may be a career limiting move on your
part...

I had this problem as well and in the end had to pollute ourselves and
allow underscores. Part of the problem is that Exim doesn't do a 5xx error
but a 4xx temporary error so the (dumb) windows machines just keep on
trying... and trying and trying.

Better thing to do would be to have some way of catching them and send a
notice to sending user and postmaster every time that their systems and/or
administrators :-) are misconfigured. Or have option to reject with a 5xx
error so the sender knows problem straight away.
