SMTP Proxy

All,

I am new to Endian coming from Smoothwall and I just had a question in regards to SMTP proxy.  I currently have Endian doing all the internet facing smtp which then forwards to my internal exchange server (which is working great).  My question is in reguards to outbound mail.  Currently all my systems are pointing to the exchange server.  Exchange server processes mail and then sends all outgoing mail (destined for inet) to enidan using smtp proxy.   I would like Endian to strip all headers to make it seem as though all mail is originating from Endian.      How can I accomplish this w/o breaking anything?  Thanks in advance.
