#
# These are the custom functions that you can write to produce a value
# for any configuration keyword that you want to do clever things such
# as retrieve values from a database.
#
# Your function may be passed a "message" object, and must return
# a legal value for the configuration parameter. No checking will be
# done on the result, for extra speed. If you want to find out what
# there is in a "message" object, look at Message.pm as they are all
# listed there.
#
# You must handle the case when no "message" object is passed to your
# function. In this case it should return a sensible default value.
#
# Return value: You must return the internal form of the result values.
#               For example, if you are producing a yes or no value,
#               you return 1 or 0. To find all the internal values
#               look in ConfigDefs.pl.
#
# For each function "FooValue" that you write, there needs to be a
# function "InitFooValue" which will be called when the configuration
# file is read. In the InitFooValue function, you will need to set up
# any global state such as create database connections, read more
# configuration files and so on.
#

##
## This is a trivial example function to get you started.
## You could use it in the main MailScanner configuration file like
## this:
##      VirusScanning = &ScanningValue
##
#sub InitScanningValue {
#  # No initialisation needs doing here at all.
#  MailScanner::Log::InfoLog("Initialising ScanningValue");
#}
#
#sub EndScanningValue {
#  # No shutdown code needed here at all.
#  # This function could log total stats, close databases, etc.
#  MailScanner::Log::InfoLog("Ending ScanningValue");
#}
#
## This will return 1 for all messages except those generated by this
## computer.
#sub ScanningValue {
#  my($message) = @_;
#
#  return 1 unless $message; # Default if no message passed in
#
#  return 0 if $message->{subject} =~ /jules/i;
#  return 1;
#
#  #my($IPAddress);
#  #$IPAddress = $message->{clientip};
#  #return 0 if $IPAddress eq '127.0.0.1';
#  #return 1;
#}
