Lichfl email idle

I think you meant to ask "What is a lich's email idle?"

A lich is a type of undead creature in fantasy fiction, often depicted as a powerful sorcerer or wizard who has achieved immortality through dark magic. In the context of email, an "idle" refers to a period of inactivity or lack of response.

So, if a lich's email idle, it means that the lich (or the email account associated with the lich) has not been active or responded to emails for a significant amount of time.
