Email sender not working

[activ]

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:

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?

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.
