You can disable / limit specific types of Email alerts.

thanks. I'm aware of these abilities

But the question was to disable specific alerts.

We see, that Central recognizes the Event as an RED Event:

[MEDIUM] Alert for Sophos Central [customer]: Firewall RED tunnel down

But there are no RED Events (de-)delectable. Only Firewall Connectivity Events, which I think matches to the mails we'd like to disable. But we'd like to receive Mails about connectivity of Firewall Interfaces, but not for RED.

Can you click on a alert in Central and disable the alert there? 

yes, nice hidden feature. Looks like an exception for this particular RED only but may help.

Where do I find the Exception list? The Tab looks like it's missing where it's supposed to be.

https://docs.sophos.com/central/customer/help/en-us/central/Customer/concepts/AlertEmailSettings.html writes:

"Exceptions

The Exceptions list shows the exceptions you have set up. These change the frequency of email alerts for certain alert types.

You set them in individual alert details on the Alerts page. You can also edit them here."

It looks like the absence of the "Exceptions" tab is currently an on-going issue. 
- The 'exceptions' tab may not be visible in some Central Dashboards

The suggested workaround is the process you've used above. 

at least those mails do not come anymore after I did as witten above. for all REDs not only this one.

thanks for pointing to that KB. seems to get fixed soon.

it's back. you could perhaps update that KB.
