+	  <p>Sieve interpreter is not protected against abusive
+	    scripts that claim excessive resource usage. Fixed by limiting the
+	    user CPU time per single script execution and cumulatively over
+	    several script runs within a configurable timeout period. Sufficiently
+	    large CPU time usage is summed in the Sieve script binary and execution
+	    is blocked when the sum exceeds the limit within that time. The block
+	    is lifted when the script is updated after the resource usage times out.</p>
