I have several e-mail accounts configured in Thunderbird. I just wanted to move an e-mail from one of my e-mail accounts [A] Trash folder to another accounts [B] Inbox folder. Because the moved e-mail has been lost, Thunderbird doesn't shows it, but here's the catch: Another email appeared in the Inbox of the [B].
I found all my outgoing emails in /home/USER/.thunderbird/vzbrrs3a.default/ImapMail/imap.googlemail-1.com/[Gmail].sbd/Sent Mail, even the ones I deleted both from the sent mail folder and the trash folder.
Why does Thunderbird keep deleted e-mails?
