Steps to reproduce:
- A message arrives with an attachment EML file
- The message is filtered
Actual results:
The message is filtered according to the attached EML file headers.
Expected results:
The filter engine should stop filtering headers when the primary message's headers ends. The rest should go to the body.

I have reproduced this locally. More specifically, filtering on the message body extends to the message's attachments, since they're technically part of the multipart message body. Attachments should be filtered out from filtering (we can probably filter out body parts that have the Content-Disposition: attachment header).
Please note that searching the bodies of attached messages is by design, it was implemented for bug 1434020.
