That last may be an artefact of posting or injecting agents. For example,
the CNews injector enforces the "conventional" form of header-names. That
is OK, I think, but it would be a MUST NOT for any agent later in the
chain to make any change (and, as Russ has said, it is to be regarded as a
bug in nnrpd).

So it is being "liberal" in what it accepts.

I agree. I propose to change it, absent screams to the contrary.
But I think I will put a MAY accept (for the benefit of Gnus and the
like). Note that all single-component newsgroup-names are forbidden on the
wire, so there is no confusion if "Poster" should appear.
