Accidentally deleted .imap folder, how can I reindex?

[Les]

Should I use full folder path, or relative to the user's home?

I have tried both:

doveadm force-resync -u gandalf /home/gandalf/Maildir/.Sent
doveadm force-resync -u gandalf Sent

There was no error message, but /home/gandalf/Maildir/.Sent/.imap was not
created, and thunderbird still did not show the new messages.

Also, when I try to open an old message from the Sent folder, thunderbird
displays nothing (even not an error message) and the dovecot server logs
something like this (fqdn and ip addresses replaced):

Most interestingly, I can open any other message in many other folders. But
the Sent folder is still wrong.

Any other idea?
