Hi Anthony,
The SDLTMSSupport@sdl.com email address is a configurable setting in SDL TMS so it's not logical to have boilerplate text to warn people that the address is not monitored because this email address could be different on some implementations. For those installations where this text is required, SDL TMS already lets you add boilerplate text by customizing the Footer template which you can find under Resources.
Regards,
David
