What file system are the mix folders on?
NFSv3 over tcp to CentOS 5.3 NFS server. NFS server is using XFS on disk.
NFS is not supported by the mix format.
NFS is a guaranteed Grade A Fancy sure-thing method to corrupt any mix
format mailbox. Ditto for mbx format. Using NFS to access a mix or mbx
format mailbox is tantamont to playing Russian roulette; you WILL lose.
NFS is supported with traditional UNIX format (a.k.a. "mbox format"), but
only in a crippled mode.
This is not unique to UW IMAP and Panda IMAP. Cyrus has similar
restrictions.
Please do not allow yourself to be misled into believing that NFS is a
real filesystem. It is not, it never was, and it never will be.
Furthermore, NFS is architectually unsound as an NFS back end. NFS is a
NAS. So it IMAP. It makes no sense to layer a NAS on top of a NAS.
Sorry to be the bearer of bad news.
