Er, a) you got 30% more files on the new server (aka target), than you 
have on the old server (aka source)??

b) Or do you see them, when you login via IMAP to the the new server?

===

If a), did you ran rsync, while the source host is in production still? Do 
you use "H" option to preserve hardlinks and/or "--delete" if you run 
rsync multiple times?

If b), did you verified the duplication with a IMAP client, that does _no_ 
caching on its own or with a fresh and empty local cache / profile / ... .

Kind regards,
