I have a commercial mail filter in front of my mailcow installation and I want to add the ip’s in “Forwarding Hosts” and disable spam checks. In the past I just added in the dns name, and it auto populated itself, but on the current version; 2023-05a it gives a “Invalid host specified:” if I grab the list from the NS, add commas, it returns the same error. looked in API logs, it provides the same language.
“msg”: “Request body doesn’t contain valid json!”
The above error also comes from Swagger
DNS resolve works on the host and in docker, (just double checked), single ip’s work, more than 1 results in above.
I can add them all one by one, it’s a list of ±75 Ips, so I rather not.
As they also rotate the IP’s it would also be beneficial to allow a DNS name only?
Thanks to anybody that could help me sorting this out!
