SMTP transparent proxy not working

I'm using DynDNS on my mail server, I can send and receive emails from the Internet, I also can activate the POP3 proxy and it can stop spam, however when I try to use the transparent SMTP proxy I stop receiving emails, I tried to route the mail to the static IP address of my mail server....I'm using ASG220.

Can any one help me with this?

In order to use SMTP Proxy, you must have the MX record at DynDNS.org point at a public IP on the External interface of your Astaro. The IP on your mail server should then be a private IP on your LAN. It sounds like you need to turn DynDNS off on the mail server, switch it to a private IP and turn on DynDNS in the Astaro.
