Nothing useful as I tried to list it, but just to make sure, I tried copying a new file in and got the immensely useful:

Apr 14 09:48:15 imap(user at domain): Error: rename(/mail/domain/user//.archives.2014/tmp/1429030095.M674819P29788.shiofuki, /mail/domain/user//.archives.2014/cur/1405004806.M943913P44906.shiofuki.domain,S=36977,W=37882:2,S) failed: Permission denied

And checking again I see the above permissions are accurate but incorrect.  640 isn't right for cur, it should be 740.  

Curiously, this directory was created by t-bird, but a simple

# chmod 740 cur 

and the folder opens correctly.  Thank you, Steffen, for the help!
