TAROU: In my opinion, there is no connection between "Po,dlexjeq l.does smfkiur me,beujkf" and "Здравейте, владея японски перфектно" (the later translated from Bulgarian means "Hello, I speak perfect Japanese").
I am not sure what the original text was, but the "Po,dlexjeq..." makes no sense to me.
Maybe you could get more info from the person who wrote you this gibberish.
