Ah-ha! That's what caused it. I wouldn't have seen that error before changing to LMTP, as using mbox Postfix would have just delivered it without issue. Unfortunately I need the first and last valid UID as this is how I control which accounts are replicated. I've setup an alias for root now that uses an account in the 1010-1020 range and I'm all happy :-) -Mark
