Invalid Root Certificate for Lets Encrypt certificate [message #150335]

Hi all,
my outlook clients can no longer connect to the server as long "Trusted certificate needed" is checked in the Kerio client.
I can see the following error message in the log:

 S/MIME: Issuer (CN=DST Root CA X3) was not downloaded. Content of URI http://apps.identrust.com/roots/dstrootcax3.p7c isn't valid certificate.

How can I force the server to accept the certificate?
I use the same certificate for external access via haproxy and every checks states, that everything is ok.

Hope someone can help.

Regards
Ralf

Hi all,
I solved it on my own with these instructions:

I'm running into the same issue on Centos. But I don't have the issue of untrusted certificate on my machine. I was able to issue 2 Lets Encrypt certificates and got this error when trying the 3rd. Any more info on how you solved the issue?
