Server specific automatic DM Replies

The idea is to basically incorporate an automatic reply system for specific servers that users can use. For example, a friend server you could have "Thanks for Messaging me friend, I'll get back to you shortly " but for a game community you could have " Thank you for messaging me. I am currently busy and so will get back to you soon." I think this would be great to have as it'd mean users from those servers could get a quick reply and have it informative. Perhaps having a certain action happen after E.G block further messages until I reply or Don't send an automatic reply again for X amount of time
