CSS one-armed-config and SMTP reverse lookup problems?
I was wondering if there would be potential reverse lookup problems from other company's when we try to send mail to their mail Domains.
If I configure failover for our mail server, I am thinking if we are sending mail, there could be a reverse-lookup issue, because our mail server would be configured with public IP Addresses other than what the MX record points to in DNS.
If we originate mail from our inside users, it will originate from the service IP address and not the VIP address.

The main advantage of this configuration is that the web servers will receive the IP address of the client that made the request. This is often required by web servers' administrators for accounting purposes.
In a one-armed configuration only, the network port ( Enet0) is used on the SCA. Only this specific port can be used for this setup. Encrypted and decrypted traffic will go through the same link
