on 2. not yet, but will look into it

@faebudo@ioc.exchange thanks a lot for your idea, I could identify some more M365 by the autodiscovery approach (from 992 to 1057 now).

@Beleggrodion@swiss.social I updated the pipeline to look for gateways and use a neat autodiscover check suggested by another reply here. More M365 now
