SPLOCKER
The ultimate SPam bLOCKER
How It Works
System Requirements: To use Splocker, your system must use
Sendmail, MySQL, and PHP.
Upon receipt of an email, Sendmail (the Unix email program) passes
the message to a program for delivery into a mail box. Splocker
modifies the delivery program to check a a database and determine
whether or not the recipient has enabled "splocking" and if so,
whether or not the sender is authorized to send.
If the sender is authorized, the message is delivered.
If the sender is not authorized, he is sent an email
asking him to "unsplock" himself by visiting a web site
and entering an 8-digit code. After successfully entering
the 8-digit code, the sender is placed in the database and
permanently allowed to send messages to that recipient without
ever again being asked to verify himself.
The person whose email is protected by Splocker can add
the names of persons he wishes to receive email from. This is
referred to as a "courtesy unsplock."
Every morning, the person who is protected receives an email
showing the sender and subject of all "splocked" messages. He may
also visit his "splocker" web site and check if there are any
"splocked" messages that he would like to manually "unsplock."
If you would like "Splocker" to augment your Sendmail installation,
please fill out this form and Splocker
will be emailed to you.
