Correspondence with continuity.

A person’s handle and mail address can change without replacing the sovereign Person behind them. Personal and Presence mailbox boundaries protect different relationships and responsibilities.

A TochMail identity does not by itself establish external email transport. Available sending and receiving routes must be stated for the exact mailbox and current release.
