[Dovecot] deliver stopped working

[vwc72283 at voicenet.com]

Note to all: If you are running Dovecot on a system where any of the mailboxes are nfs
v4 mounted from a RHEL (or derivative) server DO NOT upgrade that server to an unpatched
2.6.18-164 kernel, it is very broken at this time. Not only will Dovecot fail but you're
likely to have a myriad of other problems.
