rspamd instead of grommunio-antispam, and do not build on s390x, armhf, or ppc64le (grommunio-gromox's test suite fails on s390x, py3-openapi-core is not usable on armhf or ppc64le because of dependency hell through py3-fastapi and py3-starlette)

# This script is a wrapper for Alpine Linux openrc tools, i.e. rc-service, rc-update, rc-status
|
|
# It allows to control multiple services at once using systemd-like commands
|
|
# NOTE: The info command is compatible with the systemctl output expected by grommunio-admin-api
