Precisely. I'd suggest adding the new function to your filter instead
of modifying mimedefang.pl . Also, note this excerpt from the
mimedefang.pl man page:
TESTING FILTERS
You are strongly recommended to test your filter before
installing it in /etc/mail/mimedefang-filter. To test the filter,
save it in a file (e.g. test-filter) and run this command:
mimedefang.pl -f test-filter -test
This tests the filter for syntactic correctness. If it
passes, you can install it as a production filter. (Note that the
test tests only for correct Perl syntax; it doesn’t make sure your
filter does something sensible.)
As a simple example, you could start with something like this, which is
basically a stripped-down md_graphdefang_log():
sub my_graphdefang_log($;$$)
{
return unless defined($GraphDefangSyslogFacility);
my $event = shift;
my $value1 = shift;
my $value2 = shift;
$value1 = "" unless defined($value1);
$value2 = "" unless defined($value2);
# Make values safe for graphdefang
$event = percent_encode_for_graphdefang($event);
$value1 = percent_encode_for_graphdefang($value1);
$value2 = percent_encode_for_graphdefang($value2);
md_syslog("$GraphDefangSyslogFacility|info","MYLOG,_NOMSGID_," .
"$event,$value1,$value2,_NOSENDER_,_NORECIP_,_NOSUBJ_");
}
That should work from filter_relay() onwards. It's up to you what you
want to log, as long as you don't try to access any variables that are
not defined in the current state of the milter.
