As the error states, The IP resolve sending this post does not have actually a PTR document setup, therefore you require to set the PTR document for 185.124.86.138 (it is quite usual the receiving mail server requires this). Turning back DNS is controlled by whoever "owns" the IP address, for this reason you have to probably contact Bilgehosting to collection the document for you)
