FAILED. The IPs of not all of your mail server(s) have correct reverse DNS (PTR) entries. The reverse DNS entries are:
229.97.151.178.in-addr.arpa. 229.97.151.178.triolan.net. [TTL=1800]
229.97.151.178.in-addr.arpa. 229.97.151.178.triolan.net. [TTL=1800]

Answer 1

PTR must be registered by the provider in their DNS

Answer 2

PTR is started through RIPE, only the owner of the addresses can make changes there, write to the hoster or provider's admin, he will help.
