When a user changes their password through the web mail (horde imp or squirrelmail) it appears to fail because the old password still works. Actually, both the old and new passwords work. The password change is done through the poppassd service (port 106) and I've confirmed that the duplicate password issue exists even when telneting to port 106 and changing the password directly. If you look in /var/qmail/users/poppasswd you will see a password entry for each past password. Is this a bug or an issue with my server?
