The Postfix Recovery Kit protects the following objects:
- Postfix service daemon
- Network socket of Postfix
Create one or more virtual IP addresses for monitoring mail and assign them to the inet_interfaces parameter in the Postfix configuration file. If “all” is specified for the inet_interfaces parameter, then the local loopback address is used for monitoring. The supported SMTP / SMTPS service ports supported by the Postfix smtpd daemon are 25 and 465 respectively.
- The queue directory (filesystem) Postfix uses
If you need the mailbox spool area on another file system and need to protect it, you must create the file system hierarchy for it and create a dependency between the Postfix resource and this resource. Please refer to Create Dependency with Mailbox Spool Resource.
