Jeffrey, Does the user "dukey" actually exist in your recipient table?
As you are using a VPS with plesk it looks like the mailboxes are probably made from the control panel in plesk virtual_mailbox_maps = hash:/var/spool/postfix/plesk/vmailbox Check in your control panel. btw this means now your mail server is accepting mail for your domain, but its being rejected because that user dukey isn't found.
