  This lens applies to MailScanner rules files
  The format is described below:

# NOTE: Fields are separated by TAB characters --- Important!
  #
  # Syntax is allow/deny/deny+delete/rename/rename to replacement-text/email-addresses,
  #           then regular expression,
  #           then log text,
  #           then user report text.
  # The "email-addresses" can be a space or comma-separated list of email
  # addresses. If the rule hits, the message will be sent to these address(es)
  # instead of the original recipients.

# If a rule is a "rename" rule, then the attachment filename will be renamed
  # according to the "Default Rename Pattern" setting in MailScanner.conf.
  # If a rule is a "rename" rule and the "to replacement-text" is supplied, then
  # the text matched by the regular expression in the 2nd field of the line
  # will be replaced with the "replacement-text" string.
  # For example, the rule
  # rename to .ppt	\.pps$	Renamed .pps to .ppt	Renamed .pps to .ppt
  # will find all filenames ending in ".pps" and rename them so they end in
  # ".ppt" instead.
