Good day
Thank you very much for your message.
We apologize for your trouble.
The domain is on the blacklist of our supplier. To solve the problem immediately, we have added it to our whitelist and applied for its delisting.
Additionally you have to apply for a delisting via [ http://www.surbl.org/surbl-analysis | http://www.surbl.org/surbl-analysis ]
SURBL is a reputation database for domains and is integrated as a source by many services. Internet Guard is one such service.

Hi All
We are running a zimbra web mail server [ https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fzimbox.ch%... | 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 | 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 ...
cheers
