The message cannot be rewritten. this is IMAP protocol which says that
once a message has been delivered, no changes may be made to it.
There is also no reason for rewriting: the message is already
delivered, so the headers won't be used anymore for filtering or
delivering.

If you want to know whether training worked, try this:

- - Find a message you want to retrain (and didn't retrain before)
- - Run dspam_stats for the user you're training
- - Move the message so dovecot antispam will run your retrain command
- - Run dspam_stats again: it should show the change by decreasing a
counter (one of true positive/negative) and increase another (one of
false positive/negative).
- - The DSPAM system or user log (if enabled) should also have an entry
appended that mentions Retrained

If it failed, your regular dspam logging should contain an error message.
