Autoinstaller fails to remove the psa-qmail and psa-qmail-rblsmtpd packages using yum. The problem is with the yum package that was updated in the RHEL/CentOS-6.4 release. In upcoming updates (#132413), we will update the way we work with yum to fix the issue.
Remove the conflicting psa-qmail and psa-qmail-rblsmtpd packages, ignoring dependencies:
# rpm -e psa-qmail psa-qmail-rblsmtpd --nodeps
After this, run Autoinstaller again to install the Postfix component.
