[8.940][ANSWERED] How to release email that has been rejected (SMTP)

Hi All

I've noticed that my smtp proxy rejected an email that seems to be valid. The reason for rejection was 'Rejected: RDNS/HELO (HELO lenovo-1505276a)"

The message ID  is : 054ea589977109a2 but I can't find it under /var/chroot-smtp/spool/

How can I restore the email?

Thanks
