Empty mailboxes

[Daniel Miller]

This is driving me nuts.

I need to rebuild a server - got a notification the main drive is 
failing, and it's been a year or two, so it's time.  Got a new drive, 
fresh install of Ubuntu Tantric, started installing everything needed.  
Data stored on a RAID array - nicely available separate from the 
boot/operation drive.

Did a fresh compile of Dovecot, copied over the configs from the old 
drive, mounted the RAID...and...

Dovecot starts, authenticates users - and shows empty mailboxes. Nothing 
shown.  Full panic - reboot on old drive.  All mails present.  Change 
back - no mail.

Executing "doveadm user -u username" seems to give valid results. 
Mailbox location appears correct (using mdbox).

I setup uid/gid the same - I thought it was a rights issue but 
everything looks correct.

What can I do to try to find the stupid mistake I'm making?
