I have a thunderbird account with access from three different computers. I have two issues with the account: after more or less a week the last thirtish emails trasfer automatically to trash, so I usually retransfer them to the inbox manually. BUT this week they have been permanently deleted. Not by me, the emails just disappeared... they are not in the trash. Nor in the spam folder, nor archive. I understand I cannot recover the last emails, but I would like to know why the emails are transferring to the trash automatically in the first place. I tried looking at the settings but I didn't find anything out of the ordinary. Please let me know, thanks!
