Multipart true, but not reading the parts

Hi, this is the first GitHub issue I have ever raised, so apologies if I do not follow protocol!

Essentially, I am regularly finding that Mail is unable to read my system's emails. In the case of the attached file (I have saved it as a .PNG in order to upload it to GitHub, but it is in fact a text file), Mail is saying this is a multipart email, but parts.count = 0. I am seeing this a lot - multipart emails with no parts. As a result, mail parsing is resulting in no body.

Would be great if someone can help out with this. Thanks. Neil.


Start by using the attached text sample as a multipart-email fixture and confirm why it reports parts.count = 0 and produces no body. Trace the multipart parsing entry point, then add a regression test that defines the expected parts and parsed body before considering a fix.
