# Test case
# ---------
# By default, this image is using audited FFDHE groups (https://github.com/docker-mailserver/docker-mailserver/pull/1463)
#
# This test case covers the described case when `ONE_DIR=1`.
#
# Description:
# - When custom DHE parameters are supplied by the user:
#   ~ User supplied DHE parameters are copied to the configuration directories for postfix and dovecot.
#   ~ A warning is raised about usage of insecure parameters.
