Fixes #7876
What does this do?
Fix embedded attachment processing
Why was this needed?
For attachments which are embedded within a RFC822 attachment, were unable process some attachment if they were received a long time ago.
This is down to changes in the underlying mail gem which results in slight difference in the headers which get appended to the attachment body.
This change fixes this by only matching against the body of embedded attachments, ignoring headers and any slight changes.
