#  Author's Notes: The following user settable variables need to be set as
#  follows in the user's .procmailrc before this recipe will be called.
#
#  SPAMCOPREPORT=NORMAL|QUICK|MIXED|NONE|no
#  SPAMCOPEMAIL=YourReportingEmail@spam.spamcop.net
#
#  Where:
#
#  QUICK  *  quick report spams that are already blacklisted by spamcop.
#         *  quick report spams with dangerous content.
#            (Viruses, Executable Attachments, Embedded Scripts)
#         *  quick report spams that have the spamscore at or above the spamcop
#            handshake score to spambouncer@spam.spamcop.net even if not blacklisted
#
#  NORMAL *  quick report spams with dangerous content.
#         *  report spams above the users BLOCKLEVEL to their spamcop reporting address only.
#            Requires User interaction to confirm or cancel each spam reports.
#
#  MIXED  *  quick report spams with dangerous content.
#         *  quick report spams already on bl.spamcop.net to spambouncer@spam.spamcop.net
#         *  quick report spams with a score that is at or higher than the spamcop.net
#            handshake score to spambouncer@spam.spamcop.net
#         *  Normal report spams with a score between the users BLOCKLEVEL and the
#            spamcop.net handshake score to the users spamcop reporting address.
#            Requires user interaction to confirm the report.
#
#  NONE   *  Do not report the spam to spamcop.net
#
# For QUICK reporting SPAMCOPEMAIL defaults to spambouncer@spam.spamcop.net.
# If you turn on spamcop reporting in QUICK or MIXED modes, then qualifying emails
# will be forwarded to this address. Spamcop uses the information sent to this
# address in aggragate form. If you want to notify abuse desks via spamcop, then
# you will need to signup with spamcop.net, obtain your own reporting address,
# and use NORMAL reporting.
#
# For NORMAL reporting SPAMCOPEMAIL defaults to noemail@example.com unless explicitly set by the user.
#
# See http://spamcop.net  to obtain a reporting account for NORMAL or MIXED (quick/normal) reporting modes.
# No spamcop.net account is necessary for QUICK mode reporting.

# Check to see if this message ID has already been seen.
# This avoids re-reporting the same spam.
# Note: sometimes spams can arrive via multiple routes
#       with the same message id's.
#       These duplicate spams are somewhat rare and can be
#       reported manually if needed
