 Doubts about SMTP resource
I am using R55 hf18 and offering smtp servic to external net using an antispam appliance, If I use smtp respurce to avoid external users to map directly to my antispam, ( the reason is for avoid the appliance for showing the smtp banner und post my own via the security server) then, the antisapm stops reciving data from public ip addresses ans recevie only connections from the FW module, I know this is because the security server is a proxy, but is there a configuration to use a security server and mantain original source ip address. Since the basis of a proxy is to translate source address I think this configuration I am thinking is not possible, but what else can I do for replacing smtp banner in the FW for this public service and mantain the orignal sources? |
