The command incoming() determines the delivery target (internal/external) of an email.
This command checks whether an email is delivered locally. If not all recipients of the email are exclusively local or exclusively external, two groups are formed.
The term "local" refers to recipients who belong to a Managed domain (see Mail System Managed domains).
