My set-up: Thunderbird 115 POP3 mode Unified Folder view, Global Inbox: why can I not move messages from a Zoho Mail Lite account to my local folders when I can do so with Gmail IMAP messages? ZML settings: POP3 and IMAP enabled, enabled auto delete messages. TB setting to keep messages for maximum 3 days does not delete the messages older than that from the ZML server. I want to make sure I do not lose the messages that cannot be moved into the local folder since January 29th, this is when the issue started, before that it was fine. Is there a setting that determines the retention of emails on the server that prevents TB from deleting them? Thanks
