Many mail servers require sender to be registered in "reverse DNS".
Look:
web@dimss:~$ host gw
gw.solutions.lv has address 159.148.92.164
web@dimss:~$ host 159.148.92.164
164.92.148.159.in-addr.arpa is an alias for 164.nite.lv.92.148.159.in-addr.arpa.
164.nite.lv.92.148.159.in-addr.arpa domain name pointer gw.solutions.lv.
web@dimss:~$
Here 159.148.92.164 is mapped to gw.solutions.lv in "reverse zone".
Ask your provider to add record like this for your IP-address.
