---------------------------------------
Resolution: Fixed
This turned out to be an issue in the Pattern implementation. Added workaround
to ensure that several stars are just regex'd as a single one.

> Project: JAMES jSieve

> Fix For: 0.3

>
> A Zimbra customer reported that the mail delivery thread goes into a CPU spin
> when jSieve evaluates the following rule:
> if anyof (header :matches "from"
> "**********************************************[email protected]" ,
> header :is "subject" "5" )
> {
> fileinto "Whatever";
> stop;
> }
> I'm able to work around the problem by disallowing values that contain more
> than four asterisks in succession, but this should be fixed in jSieve.
> Here's the link to the Zimbra bug:
