mp.on("attachment", function(attachment, mail){
    var output = fs.createWriteStream(attachment.generatedFileName);
    attachment.stream.pipe(output);
});

Now:

parser.on("attachment", function (attachment) {
    self.emit('attachment', attachment);
});

Need:

parser.on("attachment", function (attachment,mail) {
    self.emit('attachment', attachment, mail);
});
