Plasmoid for mailnag daemon.
Mailnag package required!
You can buy me coffee or beer on Paypal or on Liberapay
In the settings, you can specify the refresh interval and enable notification and sound signal.
Please disable notification and sound in the mailnag package settings (if you have enabled it in the plasmoid settings).
If you want to help in correcting errors or adding new functions (as well as translating the plasmoid into your language), write to me at email@example.com.
