# empty => uses the `hostname` command to get the mail server's canonical hostname
# => Specify a fully-qualified domainname to serve mail for. This is used for many of the config features so if you can't set your hostname (e.g. you're in a container platform that doesn't let you) specify it in this environment variable.

# REMOVED in version v11.0.0! Use LOG_LEVEL instead.
DMS_DEBUG=0
# Set the log level for DMS.
# This is mostly relevant for container startup scripts and change detection event feedback.
#
# Valid values (in order of increasing verbosity) are: `error`, `warn`, `info`, `debug` and `trace`.
# network => Add all docker container networks (ipv4 only)
# connected-networks => Add all connected docker networks (ipv4 only)
PERMIT_DOCKER=none
# Set the timezone. If this variable is unset, the container runtime will try to detect the time using
# `/etc/localtime`, which you can alternatively mount into the container. The value of this variable
# must follow the pattern `AREA/ZONE`, i.e. of you want to use Germany's time zone, use `Europe/Berlin`.
# You can lookup all available timezones here: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List
TZ=
# In case you network interface differs from 'eth0', e.g. when you are using HostNetworking in Kubernetes,
# you can set NETWORK_INTERFACE to whatever interface you want. This interface will then be used.
# - **empty** => eth0
NETWORK_INTERFACE=
# empty => modern
# modern => Enables TLSv1.2 and modern ciphers only. (default)
# intermediate => Enables TLSv1, TLSv1.1 and TLSv1.2 and broad compatibility ciphers.
TLS_LEVEL=
# Configures the handling of creating mails with forged sender addresses.
#
# **0** => (not recommended) Mail address spoofing allowed. Any logged in user may create email messages with a forged sender address (see also https://en.wikipedia.org/wiki/Email_spoofing).
# 1 => Mail spoofing denied. Each user may only send with his own or his alias addresses. Addresses with extension delimiters(http://www.postfix.org/postconf.5.html#recipient_delimiter) are not able to send messages.
SPOOF_PROTECTION=
# Enables the Sender Rewriting Scheme. SRS is needed if your mail server acts as forwarder. See [postsrsd](https://github.com/roehling/postsrsd/blob/master/README.md#sender-rewriting-scheme-crash-course) for further explanation.
# Add the value of this ENV as a prefix to the mail subject when spam is detected.
# NOTE: This subject prefix may be redundant (by default spam is delivered to a junk folder).
# It provides value when your junk mail is stored alongside legitimate mail instead of a separate location (like with `SPAMASSASSIN_SPAM_TO_INBOX=1` or `MOVE_SPAM_TO_JUNK=0` or a POP3 only setup, without IMAP).
# NOTE: When not using Docker Compose, other CRI may not support quote-wrapping the value here to preserve any trailing white-space.
# 1. the "[autolearning][rspamd-autolearn]" feature is turned on;
# 2. the Bayes classifier will be trained when moving mails from or to the Junk folder (with the help of Sieve scripts).

# **0** => disabled
# 1 => enabled
RSPAMD_LEARN=0
# This settings controls whether checks should be performed on emails coming
# from authenticated users (i.e. most likely outgoing emails). The default value
# is `0` in order to align better with SpamAssassin. We recommend reading
# through https://rspamd.com/doc/tutorials/scanning_outbound.html though to
# decide for yourself whether you need and want this feature.
#
# Note that DKIM signing of e-mails will still happen.
RSPAMD_CHECK_AUTHENTICATED=0
# Controls whether the Rspamd Greylisting module is enabled.
# This module can further assist in avoiding spam emails by greylisting
# e-mails with a certain spam score.
#
# **0** => disabled
# 1 => enabled
RSPAMD_GREYLISTING=0
# Can be used to enable or disable the Hfilter group module.
#
# - 0 => Disabled
# - **1** => Enabled
RSPAMD_HFILTER=1
# Can be used to control the score when the HFILTER_HOSTNAME_UNKNOWN symbol applies. A higher score is more punishing. Setting it to 15 is equivalent to rejecting the email when the check fails.
#
# Default: 6
RSPAMD_HFILTER_HOSTNAME_UNKNOWN_SCORE=6
# Can be used to enable or disable the (still experimental) neural module.
# **enforce** => Allow other tests to complete. Reject attempts to deliver mail with a 550 SMTP reply, and log the helo/sender/recipient information. Repeat this test the next time the client connects.
# drop => Drop the connection immediately with a 521 SMTP reply. Repeat this test the next time the client connects.
# ignore => Ignore the failure of this test. Allow other tests to complete. Repeat this test the next time the client connects. This option is useful for testing and collecting statistics without blocking mail.
