hi there i have a domain name running on my vps but it seems i have not made the proper configuration on the mx records.... 
By default, does anyone know how to make a mx record that points correctly? I mean over the registar in order that some email accounts i have can be 100% functional? It seems i am getting some problems in email delivery...
Thanks in advance
