You are right, there is none. You may do an RFE in upstream's bugzilla. Though there is the /etc/postfix/postfix-chroot script shipping with the Postfix rpm. > If there is not, what is your opinion about creating one ? Other than with bind I take the security advantage of a chrooted Postfix little. Especially because other than bind Postfix typically calls other applications as for instance content filters (amavisd-new comes to mind) and, very prominently, uses Cyrus-SASL for client and server SMTP AUTH. So to be able to do SMTP AUTH with a chrooted Postfix you will have to do relocate the SASL libs - just copying into the chroot is not enough (Debian i.e. has its own patches for this). Do you have a working solution for CentOS / RHEL in your pocket? Cheers Alexander
