XF 1.5 Email Bounce Log - Message Bounced Due to Spam

I am getting forum emails bouncing back due to spam content. Trouble is when I go to submit a removal request from the blacklist they want a copy of the original sent email. How can I give them a copy of the original sent email?

The email is created using a php script and therefore it isn't stored in my servers sent folder.

This message has been rejected due to content judged to be spam by the internet community IB212 - If you feel this is in error, please submit a request using the following page.
Many thanks if someone can help with this.
Ok dumb question, the bounced email log has a copy of the sent email, I just had to add back in the original Envelope-to: and Delivery-date: and then save it as .eml
