[Mailman-Users] posts going to <listname>-request, too

[Nick Seidenman]

For the past week or so mailman seems to be sending every post sent to
<listname> to the <listname>-request address, too.  Has anyone else seen
this behaviour?  I'm open to suggestions as to what would cause it and how
to correct it.  There have been no changes to the list config that I'm
aware of or that I can see.  I'm running 2.0.3, btw.

TiA,
