Mail Server SSL

I can't see Let's Encrypt tab in Add SSL window, only Other certificate.
Actually when I try to send an email, Google refuses it due to PTR (error message says)
I think SSL certificate will solve the problem but I can't use Let's Encrypt
Do you think adding PTR solves the problem?

Thanks

I used same SSL text on domain at website tab, copied and pasted, it worked

aaP_niyazisahin I did the same. I make a new webpage mail.yourserver.com and then make a SSL cert. After copy and past into mail SSL.
