I fully agree here. There's a problem. Some companies will decide (the one
that would be 'currently' using exim) to go to something that will 'cater'
to these idiots. They don't care about standards or internet protocol, they
only care about getting their business. I know, I work for such a company
and I've not told them that such a workaround exists to allow an _ in helo.

By the way, someone asked if a server just stops in responce to 501 on helo,
yes it does. Or atleast I think that specific serer is exchange.
