Out of a sick "scientific" curiosity I left the servers in the same 
"state" that is no reconstruct and I've compiled Armin Diehl's ImapCopy. 
Given that both utilities use IMAP *IF* there was an an error on either 
of the servers, it would manifest itself for BOTH copy utilities now 
won't it (assuming we're talking the same folder)?

Guess what? I get no errors, I've already done the copy three times (not 
to mention the extra speed I get from ImapCopy).

Now, why would any of the Cyruses involved in the transfer give broken 
IMAP answers to imapsync but correct ones to ImapCopy?! =:-o Just 
because Simon likes Pascal better than Perl? I doubt that. o:-) So 
something's fishy here. :-|
