Thanks,

Exim 4.04 accepted the option, but I couldn't find it in the online
docs.

Do I just need to put the underscore or is it a regexp the must contain
all the characters allowed in HELO ?

I have put :

helo_allow_chars=_

and there is still emails going through. So I suppose that's just the
chars we want to add on top of the regular ones, isn't it?
