SMTP Iron Port - Forward Source IP client to mail server

Hi,

 

We use VS to loadbalance External SMTP traffic to our SMTP Gateway. we used to use SNAT for our VS, but on the mail server we notice SNAT ip address as Source address instead of the Client IP address,

 

We'd like to use a kind of XFF (on HTTP) but which is working on SMTP requests.

 

Is there any known solution for that case?

 

Thank you

    I think iRule can help in that case, If you can assist me to create an iRule to transmit the IP Client Source address That IronPort can catch & use.
