# Test case
# ---------
# By default, this image is using audited FFDHE groups (https://github.com/tomav/docker-mailserver/pull/1463)
#
# This test case covers the described case against both boolean states for `ONE_DIR`.
#
# Description:
# - When no DHE parameters are supplied by the user:
#   ~ The file `ffdhe4096.pem` has not been modified (checksum verification).
#   ~ `ffdhe4096.pem` is copied to the configuration directories for postfix and dovecot.
