I looked more carefully at <http://postmaster.web.de/error-messages?ip=62.75.175.182&c=rdns#nordns>, and I'm guessing that web.de has decided that euve51864.serverprofi24.de is a 'generic' name rather than an independent and fully qualified domain name. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
