+qmail provides the ability to make a copy of each email that flows through the system.
+This is done using the QUEUE_EXTRA code. See qmail FAQ #8.2
+
+The qmail tap patch adds additional functionality:
+1) Specify which email addresses tap using a regex style control file. With the
+   regex function, you can specify full domains or individual email addresses.
+2) Specify which email address to send the emails to using a control file.
+3) Qmail does not need to be recompiled to change the above. Just updated 
+   the control files.
+
+The regex match is applied to both the to and from email addresses. So email
+sent to or from the addresses will be copied.
+
+The queue tap patch adds two new control files:
+
+1) control/taps
+Contains a regex style list of addresses to tap.
+
+Examples:
+a) To tap a whole domain add a line like:
+.*@domain.com
+
+
+b) To tap an individual email address add a line like:
+user@domain.com
+
+2) control/tapscopy
+Contains the email address to send the copies to.
+
+example:
+backup@otherdomain.com
+
+The tapscopy address can be a local or remote email address.
