Let me clarify - I have no way of knowing if Thunderbird would choke due to the incredibly large number of folders. The number of emails is much less the problem. I have maybe 50 folders, and maybe 200,000 total emails, and don't have any performance issues, unless (and even then they are minor and temporary) I'm setting up a new/fresh profile (takes a while for header downloads), or repairing a folder with a lot of messages. I'm trying for the life of me to see a use case for anywhere close to 1,000 folders, and am failing. That would be a major problem just from the human side. How do you find anything? But, to each their own, you must have a way of dealing with it that suits you.
