As David's said, use a non-CERN address. CERN's dodgy approach to spam
handling is the problem, because the Rivet list has to be open to public
posts and hence spam will come "from" the list. They could suppress
bounce messages which come with a list header, but when we asked about
that they gave us short shrift.

Yes, that would be great.
