[8.940016][SMTP PROXY] How to release email that has been rejected

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
