Description

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"
"**********************************************[e-mail]" ,
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:
