In fact, the first I heard about it was today when a friend directed me to http://www.lycos.co.uk/ after spotting consistent bounces for that domain - "The server isn't even taking connections". The further information page doesn't really tell us much more.
Further investigation suggests this is a pan-european service withdrawl. I'm not much of a multilinguist but these pages all seem to be saying the same thing:
- http://www.lycos.de/
- http://www.lycos.dk/
- http://www.lycos.es/
- http://www.lycos.fr/
- http://www.lycos.nl/
I couldn't find any information on http://www.lycos-europe.com/ either. Curiously this seems to have not affected LYCOS.com which is still offering email services.
You may have already heard of this and taken appropriate steps. If not, and you're using a mailing service with a strict bounce policy, I'd avoid sending to these domains until you've discussed it with your service provider.
