[Dovecot] headers don't match message

[Kevin]

the other day i moved all mail functions to a different machine.  i
copied over my existing maildir's and installed
dovecot-stable-20050405.

once i had everything moved and dovecot running i checked my mail via
imap.  all the messages appeared however when i try to read a message
the message body doesn't match the header info that's showed in the
message list.

is this an index problem?  or did i corrupt my maildir when i moved it
over to another host?
