SSL wont work

Hello everybody,
Today my SSL certificate expired and I replaced it with a new one.
Since then i am not able to send emails via TLS - Mailserver EXIM.
The certificate is issued by Sectigo and is a wildcard.
The old certificate was from Combodo.
Now I thought to myself that the ROOT CA might not be available on a Fedora 25 and a CentOS 7 server.
I tested from this server as follows:
gnutls-cli -s -p 587 172.20.5.100
The result:
*** Starting TLS handshake
- Certificate type: X.509
- Got a certificate list of 1 certificates.
Certificate [0] info:
- subject
CN = *. example.com ', issuer
C = GB, ST = Greater Manchester, L = Salford, O = Sectigo Limited, CN = Sectigo RSA Domain Validation Secure Server CA', RSA key 2048 bits, signed using RSA-SHA256, activated2020-05-15 00:00:00 UTC ', expires
2022-08-13 23:59:59 UTC', SHA-1 fingerprint `5361b099b238be2cc50aecffdb50494dc8c04809 '
Public Key ID:
f21f313a5991b447512b9468984398b6df62d2ca
Public key's random art:
+ - [RSA 2048] ---- +

| + + .o =. . |
| . . o + o. |
| . o. |
| .oS. + |
| .o = +. o |
| . + = .. |
| E o. |
| . |
+ ----------------- +
- subject
Status: The certificate is NOT trusted. The name in the certificate does not match the expected.
*** PKI verification of server certificate failed ...
*** Fatal error: Error in the certificate.
*** Handshake has failed
Obviously the issuer disagrees.
I then imported the Sectigo ROOT CA onto both servers. The mistake remains the same.
What I also noticed there is that the ISSUER is also called differently in the ROOT CA.
In the certificate: CN = Sectigo RSA Domain Validation Secure Server CA
In the ROOT CA: CN = USERTrust RSA Certification Authority
I have no idea how to solve this problem anymore.
Maybe I'm on a completely wrong path.
Anyone have an idea?

Hi all,
as i wrote. Wrong path...
The problem was, the JAVA keystore was that old, that the newest CAs where not in.
What means, it was a java not exim problem.
I use a JAVA program to send mails. I missed that fact in my first post.I imported the CA's an all is running smooth as before :-)
regards
