variables like $PARENT_DOM or ${PARENT_DOM} don't work on Default Settings For Sub-Servers - Mail for domain

Hi, After reading this article on documentation http://www.virtualmin.com/documentation/id,template_variable_listing

and also reading changes of virtualmin 3.70 http://www.webmin.com/vchanges.html

I tried to write a custom message on Default Settings For Sub-Servers - Mail for domain - Email message to send upon server creation

Variables ${DOM} ${USER} ${PASS} work but ${PARENT_DOM} is outputted untouched and $PARENT_DOM outputs a large integer.

Can you please look into it!

Could you also add here http://www.virtualmin.com/documentation/id,template_variable_listing

exactly which variables are valid that have a prefix PARENT. For example is PARENT_USER valid? .. or maybe a way to list all available variables These variables seem a very strong feature and I intend to use it a lot..

Thanks!
