Hi All,

Hate to just be a "Me too"-er, but I have also seen these cropping up in the 
last few days. Have searched google and google groups but have not found any 
more detailed info (other than possible invalide domain names in header, 
perhaps with an umlaut) on what is causing it or how to prevent it. Would 
appreciate anyone who has some useful info posting.

Thanks,  Tom Rupprecht
