I am triyng as well to set email notification on my gmail account, but I still can't do it work, even with your advices...
Could you send me the screenshot of what you've put into the notification tab on OMV ? What should be the sender and recipient email cases ?
Thanks for your help!
The sender should be the email address you would like to use to send the email. The recipient should be the email address you'd like to get the notification on. They can be the same email address.
