For the life of me, I can't find where Thunderbird keeps track of whether or not an email I've sent has been read. Yes, I get read receipts, but I remember in Outlook, I could check to see who read a particular message. Is this available in Thunderbird? And if not, is there an add-on that does it? The one Mozilla suggests
old, and won't work with the current version. Thanks.
I need to migrate about 5gb+ of email from the local folders in Thunderbird to IMAP in Thunderbird. There are a lot of folders and a lot of subfolders, and migrating them "manually" has really been a pain in the ass. I've got about a third of the folders over, but I'd love to hear a better solution that will actually keep the folder structure in place correctly, not randomly. Perhaps there's an add-on for this? Cheers.
