    abstract =  {This document describes the "environment" and "ihave" extensions to the Sieve email filtering language. The "environment" extension gives Sieve access to information about the environment where the Sieve interpreter is running. The "ihave" extension provides a means to write scripts that can take advantage of optional Sieve features but can still run when those optional features are not available.},
