You need an Email provider that allows you to access SMTP directly in order to send out mails (or use vendor product "x" with accompanying horrible API "y").GMX in particular doesn't offer that access unless you pay for it so a Google Mail is a good alternative to that (and yes you can send it to GMX then, too).Most companies may already have a sane mail provider to use though.Cheers,Franco
Well each OPNsense uses this API for the Announcement Widget:/api/core/dashboard/product_info_feedIt uses this link:https://github.com/opnsense/core/blob/bd037cc6555b5953241760553cb72e6d6147d3da/src/opnsense/mvc/app/controllers/OPNsense/Core/Api/DashboardController.php#L219https://forum.opnsense.org/index.php?board=11.0&action=.xml;limit=5;type=rss2Any tool that turns RSS into an Email for you could be used here. Even Outlook can subscribe to them.
