The server is a 9front server. I never had any issues like that, and I also didn't change a thing recently. The only thing I did was running acmed to update the certificate for https (imap4d uses another cert iirc, which I manually checked in my mail client: it isn't signed by a CA). Surprisingly, my mail client still works as expected. It's just the notification popping up every now and then, and it can't connect at that point, but a few minutes later it works fine. I can also receive and send mail (like this one). Does someone know what could cause this? I didn't investigate further yet, as I didn't have the time, but if someone has a hint I'd be happy. Have a nice day sirjofri
