The ``WILDCARD_SENDERS`` setting is a comma delimited list of user email addresses that are allowed to send emails from any existing address (spoofing the sender).
The ``AUTH_RATELIMIT`` holds a security setting for fighting attackers that
try to guess user passwords. The value is the limit of failed authentication attempts
that a single IP address can perform against IMAP, POP and SMTP authentication endpoints.
The ``AUTH_RATELIMIT_IP`` (default: 60/hour) holds a security setting for fighting
attackers that waste server resources by trying to guess user passwords (typically
using a password spraying attack). The value defines the limit of authentication
attempts that will be processed on non-existing accounts for a specific IP subnet
(as defined in ``AUTH_RATELIMIT_IP_V4_MASK`` and ``AUTH_RATELIMIT_IP_V6_MASK`` below).
If ``AUTH_RATELIMIT_SUBNET`` is ``True`` (default: False), the ``AUTH_RATELIMIT``
rules does also apply to auth requests coming from ``SUBNET``, especially for the webmail.
If you disable this, ensure that the rate limit on the webmail is enforced in a different
way (e.g. roundcube plug-in), otherwise an attacker can simply bypass the limit using webmail.
The ``AUTH_RATELIMIT_USER`` (default: 100/day) holds a security setting for fighting
attackers that attempt to guess a user's password (typically using a password
bruteforce attack). The value defines the limit of authentication attempts allowed
for any given account within a specific timeframe.
The ``AUTH_RATELIMIT_EXEMPTION_LENGTH`` (default: 86400) is the number of seconds
after a successful login for which a specific IP address is exempted from rate limits.
This ensures that users behind a NAT don't get locked out when a single client is
misconfigured... but also potentially allow for users to attack each-other.
The ``AUTH_RATELIMIT_EXEMPTION`` (default: '') is a comma separated list of network
CIDRs that won't be subject to any form of rate limiting. Specifying ``0.0.0.0/0, ::/0``
there is a good way to disable rate limiting altogether.
The ``TLS_FLAVOR`` sets how Mailu handles TLS connections. Setting this value to
``notls`` will cause Mailu not to server any web content! More on :ref:`tls_flavor`.

The ``RECIPIENT_DELIMITER`` is a character used to delimit localpart from a

The ``RECIPIENT_DELIMITER`` is a list of characters used to delimit localpart
from a custom address part. For instance, if set to ``+-``, users can use

to deliver mail to ``localpart@example.com``.
This is useful to provide external parties with different email addresses and
later classify incoming mail based on the custom part.

Mailu can serve an `XML file for autoconfiguration`_; To configure it you will need to:
1. add ``autoconfig.example.com`` to the ``HOSTNAMES`` configuration variable (and ensure that a valid SSL certificate is available for it; this may mean restarting your smtp container)
2. configure an override with the policy itself; for example, your ``overrides/nginx/autoconfiguration.conf`` could read:

### Don't create an open relay !
As a side effect of this ingress mode "feature", make sure that the ingress subnet is not in your RELAYHOST, otherwise you would create an smtp open relay :-(
### Ratelimits
When using ingress mode you probably want to disable rate limits, because all requests originate from the same ip address. Otherwise automatic login attempts can easily DoS the legitimate users.
## Scalability
- smtp and imap are scalable
