I tarred up my Maildir from one server and untarred it on another, I had hoped it would work, It partially does. It has all my messages but doesn't show the subdirectories in Thunderbird.

Maildir# ls -l .INBOX.car total 44 drwx------ 2 rjl 1000 4096 Feb 15 2014 cur -rw------- 1 rjl users 17408 Jan 18 02:10 dovecot.index.cache -rw------- 1 rjl users 1040 Jan 18 02:10 dovecot.index.log -rw------- 1 rjl 1000 23 Aug 26 2011 dovecot-keywords -rw------- 1 rjl users 1683 Jan 18 00:20 dovecot-uidlist -rw------- 1 rjl 1000 0 Aug 4 2011 maildirfolder drwx------ 2 rjl 1000 4096 Aug 4 2011 new drwx------ 2 rjl 1000 4096 Feb 15 2014 tmp

Maildir# ls -l .INBOX.car.Enterprise/ total 40 drwx------ 2 rjl 1000 4096 Jul 3 2013 cur -rw------- 1 rjl 1000 20480 Mar 20 2014 dovecot.index.cache -rw------- 1 rjl 1000 1824 Mar 20 2014 dovecot.index.log -rw------- 1 rjl 1000 212 Jul 10 2013 dovecot-uidlist -rw------- 1 rjl 1000 0 Jul 2 2013 maildirfolder drwx------ 2 rjl 1000 4096 Jul 2 2013 new drwx------ 2 rjl 1000 4096 Jul 5 2013 tmp

Thunderbird displays the files under: .INBOX.car/cur/

but not .INBOX.car.Enterprise/cur

Is there any way to rebuild the subdirectories?
