50
|
|
|
|
|
|
|
free e-mail provider such as hotmail.com or yahoo.com. It |
51
|
|

=head1 DESCRIPTION |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
This module can be used to screen credit card orders based |
57
|
|
|
|
|
|
|
on e-mail. Many credit card scamsters use free, anonymous |
58
|
|
|
|
|
|
|
email accounts with another person's name to place fraudulent |
59
|
|
|
|
|
|
|
orders. |
