nsupdate/nsupdate.sh
Stefan Bader 10127f462e added support for mx records:
set MX=YES in your .config file if the DOMAIN specified in
	the .config file is actually an mx record.
	currently only supported when using nslookup and not drill.

added SILENT mode:
	if SILENT is set to NO the output and the logmessages
	remain the same.

	if SILENT is set to something else than NO or not set then
	neither will there be an output nor a log message as long
	as the ip-address doesn't change
