Hello,
I'm using a Astaro 120 which has replace a Juniper SSG5. I want to use the Astaro SMTP Proxy to filter Spam and AV. My SBS2003 server sits behind the Astaro on a private address.
The Astaro's interface's are on xx.xx.xx.202 and xx.xx.xx.146 as I have two DSL connections. my MX records are xx.xx.xx.203 and xx.xx.xx.146. These currently are additional address within the two main interfaces and I have DNAT rules inplace to translate the addresses to the private address of the server on 192.168.90.1. finally I have Packet Filtering rules to allow SMTP traffic from Any address to the private IP of the mail server.
All is working find however when I switch on the SMTP proxy no data is being received by the Astaro... is this because the Astaro can only reveice mail on the main interface and not Additional ones? i.e. do I need to change the MX records to 202 & 146?
Last point we have over 18 domain all receiving mail on the 203 and 147 addresses so not changing the MX records would be best...
JC
