[New-bugs-announce] [issue31524] mailbox._mboxMMDF.get_message throws away From envelope

[bpoaugust]

New submission from bpoaugust:

https://github.com/python/cpython/blob/master/Lib/mailbox.py#L778

The code here reads the first line, but fails to save it as the unixfrom line.

Alternatively perhaps it should reset the file back to the start so the message factory has sight of the envelope.

The end result is that the envelope is lost.
