Pigeonhole Sieve: Variables Extension
=====================================

The Sieve *variables* extension (RFC5229 [http://tools.ietf.org/html/rfc5229/])
adds the concept of variables to the Sieve language.

Configuration
=============

The *variables* extension is available by default. The *variables* extension
has its own specific settings. The following settings can be configured for the
*variables* extension (default values are indicated):

sieve_variables_max_scope_size = 255 (v0.5.0+) :
  The maximum number of variables that can be declared in a scope. There are
  currently two variable scopes: the normal script scope and the global scope
  created by the "include" extension. The minimum value for this setting is
  128.

sieve_variables_max_variable_size = 4k (v0.5.0+) :
  The maximum allowed size for the value of a variable. If exceeded at runtime,
  the value is always truncated to the configured maximum. The minimum value
  for this setting is 4000 bytes. The value is in bytes, unless followed by a
  k(ilo).
