Fine the OpenSSL command-line utility that matches the library
Postfix is linked with. Then:

        openssl version -d

For example, on a RedHat system:

    $ /usr/bin/openssl version -d
    OPENSSLDIR: "/usr/share/ssl"

Then look for a cert.pem file in that directory, and a certs/
sub-directory, (which is only effective if someone runs c_rehash
there). You can confirm via:

    $ strings -a /usr/lib/libcrypto.so | grep /usr/share
    OPENSSLDIR: "/usr/share/ssl"
    /usr/share/ssl/private
    /usr/share/ssl
    /usr/share/ssl/certs
    /usr/share/ssl/cert.pem
