Hi Tobias,
We were not directly impacted, but a customer of ours was hit in the same way (we're the hosting company, so when they saw SSL warnings, they directly contacted us). I pointed them to the delisting page.
I didn't contact Swisscom directly, but the site's webmaster did. It seems it usually takes 2-3 weeks to be delisted. By being very persuasive, she was able to get the website unlisted in a day. She couldn't get a reason for the listing.
I'll try to get information on how she actually managed that.
Good luck with this. It obviously had to happen on a Friday...
Kind regards, Florian

Hi All
We are running a zimbra web mail server https://zimbox.ch for our customers. Yesterday afternoon swisscom has put its IP (46.140.183.201) on their DNS blacklist (https://www.swisscom.ch/de/res/hilfe/internet/internetguard/url-checker.html). Since the thing is running https, this leads to people with swisscom internet access to get some cryptic error message about SSL problems from their browser when they want to read their mail.
No, the server is not hacked, and we are running the latest version of zimbra web mail on it.
We have filled in the swisscoms 'de-blacklisting' web form but nothing has happened yet. We also called the swisscom kmu-hotline, but no, sorry we can not do anything.
Any advice ? For now we are advising our customers to set their dns server in their computers to 8.8.8.8 ...
By the light of day, swisscom is directly damaging our business with this ...
