Loopback with virtual IPs

Hi I currently have the last version of pfSense 2.1 and I have this infrastructure.
I use virtual IPs and I use NAT 1:1 to open ports to internal IPs.
Ex: 22.214.171.124 -> 10.0.0.100
Then I add rules on Rules sections. The port opening works great.
I have a mail server on 10.0.0.100 wich it's domains is mail.domain.com but the reverse address of mail.domain.com is 126.96.36.199 so when I send any email the postfix tries to connect to mail.domain.com wich the address is requested to a public DNS and it returns the public IP but I can't connect from 10.0.0.100 to 188.8.131.52 wich is the same IP but the pfSense structure doesn't let me communicate with my self.
Maybe I explain horribly but I hope you get it.
Is there a way I can access to 184.108.40.206:25 from 10.0.0.100?
Or I should implement an internal DNS?

You should use split DNS in situations like this. For a small number of addresses, you can use the overrides in the DNS page for specific domain names.
