Not sure if this is a real email or a bad and rude joke

Considering the address is on the domain for the original post and the poster says it's his third language... perhaps, just this once, it's safe not to assume malice.

Yep, real email. Not sure what the rude part was..

I think it's funny and clever use of his domain name. I suppose he uses it as a kind of action inbox /to-do later list.
