postmulti

/usr/sbin/postmulti
Postfix multi-instance manager

The postmulti command allows a Postfix administrator to manage multiple Postfix instances on a single host. postmulti implements two fundamental modes of operation. In iterator mode, it executes the same command for multiple Postfix instances. In life-cycle management mode, it adds or deletes one instance, or changes the multi-instance status of one instance.
