You open a file, assign a reference to nmsg, then promptly overwrite the
variable with the message, thereby closing the file.

If you want to use a file for this, you need to write the message to the
file, rewind it, and pass the file variable to rfc822.Message:

nmsg = open('inbox','w')
for ln in mserver.retr(1)[1]:
    nmsg.write( ln + "\n" )
nmsg.seek(0)
rmsg = rfc822.Message( nmsg )

If you'd rather not use a file, you can use StringIO to do the same thing.

sio = StringIO()
sio.write( join( mserver.retr(1)[1], '\n' ) )
sio.seek(0)
rmsg = rfc822.Message( sio )
