After long searching, i got a useless solution.
I can send emails to non-gmail emails because my vps ip is black listed.
My friend (vps expert) told me that my vps from Choopa which was used by spammers before.
Any solution? How can i get my vps ip unblacklisted?

I don't think your IP has been blacklisted - your host has confirmed this as well.  What I do think is that your reverse DNS hasn't been correctly configured for SMTP delivery.  Have you set up a PTR record?  Check the suggestion at the link below of how to fix the problem:
