Can you use NLP to make out of office delays more exact? Reads OOO response, determines the date when they're back and sets up the delay for X days or hours after that return date. Or if there isn't that information for some reason, it defaults to a pre-determined number of days like how it's currently structured. This could probably work for other forms of auto-replies as well, like if someone doesn't work at the company anymore, things like that.
