Reverse DNS needs to be set up

The error is saying that the reverse DNS lookup for your mailserver failed. This is a lookup the recipient's server does to be sure the name & IP of the sending server is "legitimate" by seeing if it matches what is in DNS. Be sure the server sending your messages has an MX record that matches the name/IP from which it is sending. If this MX was recently added, it can sometimes take a day or two for it to replicate out into the public.
