Chroot is not enabled by default in the standard Postfix distribution.
Some "helpful" maintainers of Linux distributions DO enable chroot by
default.
$ egrep "^[^\#].*smtpd" /etc/postfix/master.cf
smtpd pass - - n - - smtpd
submission inet n - n - - smtpd
The fifth column should say "n" if chroot is disabled.
Also, check the permissions of /opt, /opt/ema, AND /opt/ema/sockets to
make sure the postfix user has access.
