The size of this file should be 6494 bytes (S=6494) but in your attachment it is 6519 bytes. Did something insert a header into the file after dovecot received it? Perhaps this one, which (with a CR added) is 25 bytes, the same as the difference between 6519 and 6494: X-Spambayes-Trained: ham
As I understand it, once messages are under dovecot's control they must not ever change at all. Adding headers after delivery is forbidden.
