Hi,
IMHO segregation is the key, I would put a mail server in yr DMZ (which provides virus 
and maybe content scanning) and then have another mail server in yr internal net which 
initiates connections with the MS in the DMZ. 
Have yr FW do the NATing.


internal net--------->internal------------>Firewall------------>internet
                            mail server              |
                                                           |
                                                           |
                                                          \/
                                                     mail server
                                                        DMZ

Kind Regards

Hi There

Can somebody please shed some light.

Is it safer to place your mailserver in the DMZ or in your LAN (with NAT
configured)?

Thank you

Imraan
