The plug-in checks customer credit card data, namely, whether the email address entered by a customer as cardholder mail is in black list or not.
To configure the plug-in:
- Open System > Settings > Fraud Screening.
- Select the Black List of E-mail Addresses plug-in by clicking the respective link in the Plug-in Name column.
- Click Add New Pattern. Fill out the form:
- Select an email pattern type from the Pattern Type group by switching either in the Email Address or in the Regular Expression position. The selected Email Address option will make Billing consider data you input in the Email Pattern field as a full email address. The selected Regular Expression option allows you to specify certain expression in the Email Pattern field, Billing will check whether a customer's email address fits the pattern, represented by the expression and, if so, considers such email address as suspicious.
- Input either an actual email address or a regular expression into the Email Pattern field.
- To enable the pattern, select the Enabled option. Before pattern is enabled it is listed in the patterns list but remains unavailable for using in fraud screening rules.
- Click Save to confirm changes.
Note: Under specific configuration of fraud screening, the following problem may arise: when a payment is refunded, all its parameters are put into the black lists that are configured (e.g. the customer credit card, black list of service plans, etc). To handle the situation, after refunding, the staff member must adjust the black lists if required (for example, if the credit card is not supposed to be included to the list, staff member must delete it from the list manually after refunding the payment).
