So you know. Configuring SMTP for sending emails is a bit tricky with secure connections. See below for correct config in the config.production.json file: "mail": { "transport": "SMTP", "from": "'Mickey Mouse' xxxxx@probablynotinteresting.com", "options": { "host": "ms.xxx.com", "port": 587, "secureConnection": false, "requiresAuth": true, "tls": { "ciphers": "SSLv3" }, "auth"
