    Do you remember in the early days of the net using backslash bang syntax?

    Virtually all large corporations have such capability. In fact the
    majority of corporate sent emails are inter office. N.B. Large
    corporations usually comprise many dispersed sites and email among them
    is often encrypted bundles sent every few seconds or minutes.

    For example, governments might block the internet during a war to
    prevent hackers from spying. If you have your own mail server and only
    want to communicate with 255 people, would this be possible? Armies
    around the world would need a way to communicate with their commanders.

    Just a thought.





    A mail server can operate on a local network (LAN) without internet by
    using internal SMTP/IMAP/POP3 services.

    Email clients (Outlook, Thunderbird) need(required) to be configured to
    point to the local server's IP address for both incoming(POP/IMAP) and outgoing(SMTP).

    Email server software is necessary.
    - open source(free) may be available
    => when looking for opensource, ensure that the company and
    development is current. i.e. open source(especially free) may be
    available, but no longer developed, supported, or updated.

    Mail in the intranet works. I have it inside my home. It is easy inside
    a building. Mail with the commanders in the field is a different matter,
    you need a transport.

    One possibility is intermittent internet.
