I have now over 7GB of email (compacted) in Thunderbird. It was all fetched via POP3 and so the only copy of these emails is on my PC. Of course I backup the files etc.
What I have been thinking now, however, is that it would be ideal to use IMAP and keep the emails on the server also so that if my disk dies, I wouldn't lose anything. But I would like to upload all of my existing emails, including their file structure, into that IMAP account.
Tbird is supposed to have a feature whereby one can "move" emails from a local store to an IMAP inbox but I don't know about entire folders. Also my Sent folder is actually one my vital items--I very often review emails I sent to my clients there, to refresh my memory or for whatever reason. I would like those, as well as my Trash, online also.
Is this even possible or feasible? Am I just being stupid? It is 7GB we are talking about. Perhaps I should just forget about the upload and proceed to keep emails from today forward in IMAP on the server. Not sure how it works to re-create the folders that I have locally online, since they already exist here....
Any ideas are appreciated.
