Connecting On Premise Mail Destination and Sending Email Using SAP Cloud SDK JavaScript Version 3 on SAP CAPConnecting On Premise Mail Destination and Sending Email Using SAP Cloud SDK JavaScript Version 3 on SAP CAPMail from CAP through a company's own SMTP server rather than a hosted one, which is the case the existing answers did not cover — the author names them and says why each failed here: one needed an SMTP provider like Mailtrap, another solved it in Java. What is left is the connectivity: an on-premise mail destination reached from Node, and a hybrid profile to test it against.codebrokerad, published 2023-02-14

How to Access On-premise OData from the Business Application Studio - CAPM DevelopmentHow to Access On-premise OData from the Business Application Studio - CAPM DevelopmentA destination-naming constraint found the hard way and then corrected in public: the post carries its own update saying that with a CAPM app, a standard destination works through the studio's proxy as long as the name matches [a-z0-9-]. The update credits a comment on the post, so the correction and its source are both in the record.laszlo_kajan2, published 2020-06-02
