is there a simple way to get thunderbird to fetch them from the moment I turn the pc on and give me notifications about it?
Sure. You can autostart Thunderbird and keep it open but I haven’t found a way, where Thunderbird closes/starts to the tray and for some odd reasons the developers seem to think that users do not need this functionality which makes the whole email client unusable for a large part of the potential user base.
I can get the clients to fetch the e-mail atm, the issue is what I wrote above,
