I suggest that you not store your mail spools on NFS. Do IMAP over the network to a load-balanced imapd if you want (with GFS on shared scsi/san storage), but for heaven's sake, don't point your imapd at an NFS export. Your IMAP server shouldn't need to be load balanced anyway, so you could take that complication out of the picture if you want. Load balancing an MTA via DNS (not using MX records) seems to be asking for trouble too, although I can't put my finger on why.
