[issue12515] The email package modifies the message structure (when the parsed email is invalid)

[xavierd]

New submission from xavierd <xdelannoy at cloudmark.com>:

the function 'email.message_from_file' modifies the message structure when the parsed is invalid (for example, when a closed boudary is missing). The attribute defects is also empty

In the attachment (sample.tgz) you will find:
   - orig.eml : an email with an invalid structure The boundary
"000101020201080900040301" isn't closed
   - after_parsing.eml: same email after calling email.message_from_file()
The boundary is now closed. And the defects attribute is empty
   - test.py: python script to reproduce.
