I think I have found the reason.
It was my fault from the start.
In the new dedicated server I had old firewall config rules with masquarade enabled.
This way everything going out of the server had the source ip changed into the main server's IP. That's why the destination server saw the external IP address as the source address instead of the VM's IP and could not recognize the hostname to the address and thought that the mail was spam. Disabling the NAT and changing the rules helped...for now.
I hope that the rest of the VMs will not cry about the firewall rules changing
Stupid thing took me two weeks to figure out. Anyway, thanks for your help guys!
Have a nice day.
P.S.
If you're reading this mail from some kind of an archive and it's year 2013 already then you have greetings from the past, and I am glad that you have survived the 2012
