deploying cisco ESA as a second layer

Hai,

We have a ironport poc with one of customer. The customer need to deploy our ESA boc as behind thier existing Metcafee Email gateway, so that he need to analyse the differences.

The issue, is if i deploy ESA as second layer, the origin /sender details will miss by Our ESA box and traffic will be receiving from Metcafee only . So, i think the ESA box cannot identofy the source/ oringal sender, It will recieve the traffic from metcafee as relay.  In these case can our esa can check the SBRS or not?? Please clarrify.!!!

Regards,

fayz
