How to Add Wild Cards to Rules and VIP Lists

Asterisks may be used as wild cards in the VIP list, but not in specific rules. Asterisks must appear before the @ symbol. For example, adding *@bademail.com to a VIP decline list would cause all email addresses from this domain to trigger a decline rule.

If an asterisk is used in an individual rule, such as a rule declining *@bademail.com, the rule wouldn't trigger if fraudster@bademail.com was the email used in a transaction, because rule conditions require exact string value matches.
