There is a proper RFC 2142 for "MAILBOX NAMES FOR COMMON SERVICES, ROLES AND FUNCTIONS". This RFC was written in May 1997, is very network centric and needs some serious updating, especially for security, privacy and cloud services specific mailboxes. This is an effort to capture other common email Inbox names that security, privacy and IT teams need for communication purposes.
