Agreed.
In this case we need to sanity check what we ask for prior to asking since
we cannot depend on the library to sanity check for us.
[I already have someone complaining about domains with underscores - my
announcement here said they won't work - the fact that we have had them
blocked in the dns systems for a long time now is hardly relevant.
However like the HELO arguments it might be politic to have some way of
allowing broken configs]
