Piler is not a usual MTA. Though it speaks smtp, it won't actually relay anything. If you compiled piler with --with-tcpwrappers option (see piler -V), then use /etc/hosts.{allow,deny} files to limit access to certain smtp hosts. Another option can be using iptables on the piler host, or a network firewall.
