Based on this log line:

listenerId = "imaptls", localPort = 993, remoteIp = 161.128.195.129, remotePort = 25838, mailboxName = "INBOX/�������", accountId = 107, mailboxId = [80], elapsed = 8ms

It looks like one of your mail clients is not using UTF-8 to encode the folder name. Only ASCII or UTF-8 characters can be used on folder names, your mail client should handle the conversion automatically.
