Hosting without DNS records
|
|
===========================
|
|
|
|
.. note::
|
|
|
|
This option is experimental and might change without notice.
|
|
|
|
In case you don't have a domain,
|
|
for example in a local network,
|
|
you can run a chatmail relay with only an IPv4 address as well.
|
|
|
|
To deploy a relay without a domain,
|
|
run ``cmdeploy init`` with only the IPv4 address
|
|
during the :ref:`installation steps <setup>`,
|
|
for example ``cmdeploy init 13.12.23.42``.
|

Drawbacks
|
|
---------
|
|
|
|
- your transport encryption will only use self-signed TLS certificates,
|
|
which are vulnerable against MITM attacks.
|
|
the chatmail core's end-to-end encryption should suffice in most scenarios though.
|
|
|
|
- your messages will not be DKIM-signed;
|
|
experimentally, most chatmail relays accept non-DKIM-signed messages from IPv4-only relays,
|
|
but some relays might not accept messages from yours.
