Hi Josef Koupal Sadly this is not supported by the E-Mail Step element or our API. But as it is a System Property, I think you can easily set it by add "-Dmail.smtp.from=mail@example.com" `-Dmail.smtp.from=mail@example.com` to the configuration/jvm.options `configuration/jvm.options` file (8.0) file and start your engine. The property should then appear in the Engine system property list. This should be detected and applied to the mail session. But you need to try if this works. Regards Lukas
