Postfix daemon processes do not use root privileges when opening this file (Postfix 2.5 and later).
The file must therefore be stored under a Postfix-owned directory such as the data_directory.

The general format of the file is as follows: The expressions "$name" and "$" are recursively replaced with the value of the named parameter.
The parameter name must contain only characters from the set [a-z A-Z0-9_].
These forms are supported with Postfix versions ≥ 2.2 and ≥ 3.0, respectively.
The expressions "$" and "$" are replaced with "value" when "$name" is empty.
As a migration aid, an attempt to open the file under a non-Postfix directory is redirected to the Postfix-owned data_directory, and a warning is logged.
Examples: Enable caching of failed address verification probe results.
The expression "$" is replaced with "value1" when "$name" is non-empty, and with "value2" when "$name" is empty.
The "" is required for "value1", optional for "value2".
An undefined parameter value is replaced with the empty value.
