[Dovecot] Quota over NFS with inode limit

[Patrick Domack]

Hmm, there are no log messages for the last two weeks that say a  
rename failed for imap services at all. The user account this was  
happening on has had their quota problem fixed, and now I am unable to  
replicate it :(

The only thing I did notice is the user was at 1 inode below thier  
hardlimit, and wasn't anywhere near their block limit.

I guess this is going on hold till I can replicate the issue again,  
but here is some log info, and I didn't see any notice in postfix  
about looking for this error code, but it sees it and bounces on it,  
so maybe I should dig into it's code some more.

occurred. Refer to server log for more information. [2009-06-08
