Hi all Just received this update from UPC:
Many thanks for your e-mail. We reported this greylisting issue to our mailserver administrators. They will take care of it and hopefully resolve this issue within the next week.
We added the 6 IP's of the outgoing mailservers to the DNSWL.org Whitelist. 84.116.36.91 vie01a-dmta-ch01-1.mx.upcmail.net 84.116.36.92 vie01a-dmta-ch01-2.mx.upcmail.net 84.116.36.93 vie01a-dmta-ch01-3.mx.upcmail.net 84.116.36.94 vie01a-dmta-ch02-1.mx.upcmail.net 84.116.36.95 vie01a-dmta-ch02-2.mx.upcmail.net 84.116.36.96 vie01a-dmta-ch02-3.mx.upcmail.net Many thanks for your understanding.

Quick update on that case. UPC Switzerland is fully aware of the problem. The Mail-Platform in the Netherlands is operated by UPC Austria (probably chello.at). And they still deny that there is a problem on their side and blame the ISPs that do greylisting. UPC Switzerland is trying to escalate the problem. Regards -Benoît Panizzon-
