Hey Homeys, I am trying to get the email sender to work, so I installed it and configured an account etc. When using the test button I get: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/8/f8d99f5e6d148b141f974a09743af8146c4c89eb.png) But when using it in a flow I get the error: Mail command failed: 530 5.7.0 User not authenticated. Anyone have an idea what is going on here? ---

Found my own solution. I restarted the app and now it works. ---

Did you check the existing thread about this? > [@Email sender app not sending mail?](https://community.homey.app/t/email-sender-app-not-sending-mail/11360): > > I have installed and configured the Email Sender app. When testing the configuration (on the apps configuration screen), it gives a succes message and I can see the message coming in at my synology mail. When setting up a flow, even a simple one, it does nothing. The action seems to keep running (rotating disc), nor do I see a message in the SMTP logs of the Synology. Is there a way to troubleshoot further? It suggests that you should restart the app after configuring settings.
