Hi

You can try something like below:

String theValue = " Proprietary information hidden, Proprietary information hidden";     String[] test = theValue.split(",");     for (int i = 0; i < test.length; i++) {     try { javax.mail.internet.InternetAddress emailAddr = new javax.mail.internet.InternetAddress(test); emailAddr.validate(); } catch (javax.mail.internet.AddressException ex){ return false; }         }     }

The String "theValue" will be the actual value from the property, so that can be removed in your rule.

Regards
