The idea is not to be "sure", but to actually check with "ldd".

Well, in that case perhaps Exim is not loading the default CA locations,
or there's some sort of file access control (SELinux? AppArmor? ...)
that's preventing Exim from reading the directory.

You'll have "strace" Exim and see what it is doing when it fails
to verify the peer chain.

Did you share the destination domain name at any point? Perhaps
its certificate chain really does have some sort of issue.
