The problem is also that the 500 error message from poppassd which is displayed 
in passwd is quite cryptic so the user doesn't have a clue what went wrong. 
Only the pam error message in syslog gives more info:
PAM error: Password will be truncated to 8 characters
PAM error: Sorry, passwords do not match.
