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? ---

A simple flow that only sends an e-mail also does not work. ---

When I test the configuration, it works. Only not in a flow. I am using the SMTP server on my Synology NAS. But the message is never even queued on the NAS. Strange. ---

Try restarting the app on your Homey after saving the settings. There seems to be a bug in it which I haven’t been able to track down yet. ---

I have the same issue with Email sender. In settings it work fine, and i can read the testmail in mailbox, but in flows it take a time and then time out. I have tested with two different e-mail servers, one of them Gmail. I have removed and reinstalled the app for two times and restarted the Email sender-app many times. I run it on a brand new Homey Pro. ---

Now Email sender works for me, but when I test the flow the busy rotation icon on the card seems to be there long time after the mail is sent. Mayby that tricked me a lot during my error-working. ---

> [@Morgan\_Gunnarsson](#): > > Email sender The same problem here too, has been going on for 3 days with different variants and mail servers, but none of the variants have been working in a Flow. Also reinstalled the app. But still no luck getting the app to work in a Flow. NB: worked before, but just stopped working for a couple of months ago. Testing with the app setting works without problem. ---

We never learn to go for the easy parts first. 😊 Here I have wasted several days with nothing but nonsense. Then it was just a matter of turning it off and on again. Is there an app and routine that restarts Homey every week, I think this is necessary. ---

Anyone else with more information? I have tried with restarts and uninstall/install (and different email providers). Keep getting: Error: Invalid login: 535 Authentication Credentials invalid. Any clues/ideas? //Jan
