When we do a test on www.internet.nl/.../*ourdomain* we are getting the following errors back:
Key exchange parameters:
At least one of your mail servers supports insufficiently secure parameters for Diffie-Hellman key exchange.
And the following:
At least one of your mailservers does not enforce its own cipher preference ('I').
our domain : none
We are using Sophos UTM 9 version 9.707-5
How can we fix the errors on test?
