[Lava-users] Help: job email notification log and deivce state change command

Hello everyone, Can you help me on below two questions?

1. I did email notification settings for sending emails after job complete or incomplete. How can I get whole logs (where are logs?) about email sending process? I need to debug email sending.

2. I want to use script to control device state periodically. How can I set device to maintenance state using command, like lava-tool command?

Thanks in advance.
