# su cyrus
# /usr/bin/cyrus/bin/ctl_mboxlist -d > /tmp/mboxlist.txt[*]Edit the text file and remove the lines that contain the problem folders:

[*]Create a fake imap email account. Don't use a real name or password. We want the account to remain offline.
[*]Quit Mail
[*]In the Finder, open the directory holding the newly-created INBOX.imapmbox file (It's in ~/Library/Mail/IMAP-something/").
[*]Move this (empty) INBOX.imapmbox to the trash.
[*]Move the cached mail file you had copied to the Desktop to this folder. Rename the file to "INBOX.imapmbox".
[*]Start Mail again, and click on the new account name. Your messages should reappear.
[*]Copy the messages from this folder to another one, either IMAP or locally.
[*]In Mail's preferences, delete the account you had created.
Make sure you keep this fake account offline, or else Mail will overwrite your cached mailbox with an empty one! 继续 BS
