good morning Still problems after upgrading to 7.6.4. Since I updated to 7.6.4 infrastructure Meg, I have many problems on the TLS connection that is rejected by some domains MX. The certificate is valid and is the CA: Do you also have problems of this type? following what is happening;

Its possible that the root CA cert needs to be re-hashed. The easiest way to do this is to just re-import the CA certificate.
