Thanks. That was helpful. The issue was the smtp_url. In the debug output I saw the line External authentication name: jeff But that misses the user's domain name. So I needed to change set smtp_url = "smtp://jeff@MY_MX_HOST:587" to set smtp_url = "smtp://j...@p27.eu@MY_MX_HOST:587" Indeed, adding the password helped as well. set smtp_url = "smtp://j...@p27.eu:SECRET_password@MY_MX_HOST:587" Thanks!
