I’ve got SpamSieve set up as a spam-catching drone, but somehow the drone got misconfigured. It used to place spam into the IMAP folder “INBOX/Spam”, but now it is putting it into “INBOX/INBOX/Spam”. (I think the problem started when I began mucking around with Mail’s Mailbox > Use This Mailbox For commands on the non-drone.) This has led to various other problems, such as preventing the AddToSpam and AddToGood scripts from working.
All of Mail’s settings seem correct, and going through the “Spam Sieve - Change Settings” didn’t help. I’ve decided I need to reinstall SpamSieve. I probably need to delete and recreate my IMAP account in Mail as well.
The only problem is my corpus. How can I do all this reinstalling without losing my corpus? (I’ve spent months training it and don’t want to lose it.) Is it as simple as saving a copy of the corpus, reinstalling SpamSieve, and then copying the corpus back to its original location? If so, which files do I need to preserve?
