So I looked into this a bit more and based on http://www.postfix.org/postconf.5.html#smtp_tls_CAfile is doesn't appear to me that the ca-certificates.crt file needs to be in the chroot at all. What happens if you just delete the chroot copy? Looking in the git history, I can see we used to install this file into the chroot, but I'm not sure we needed to.
