[swinog] What blacklists does @bluewin.ch use

Hello List

A Mailserver from a business customer of ours is blacklisted @ bluewin. The Error Message from Bluewin MXes directing to the removal site: https://www.swisscom.ch/en/res/hilfe/ip-blacklist.html

Our customer has requested removal via this form, no success.

Our customer has contacted bluewin and opened a trouble ticket. He got the information that his ISP (us) should take care to remove his IP from the blacklists, but is not getting any information about which blacklists.

Blacklisted: 0

We are at a loss. Does anyone know what kind of blacklists bluewin uses?

Kind regards
