Postﬁx plays a variety of roles, all critical to the proper flow of email. It listens on the network for incoming mail, transports mail messages to other servers, and delivers local mail to a local program.
The LifeKeeper for Linux Postﬁx Recovery Kit provides a mechanism to recover Postﬁx from a failed primary server to a backup server in a LifeKeeper environment. Both LifeKeeper and Postﬁx ensure data integrity throughout the course of the failover process without significant lost time or human intervention.
