Hi We have an issue where email is all routing ok from outlook but when sent from UNix box the emails DO send to internal domain - but when going on to external domain from us outside LAN they are not sending? - They were working all ok when the sendmail Unix side was pointing to our exchange 2003 server - but when the unix guys changed to preferred server (exchange 2007) no. - both exch 2003 and 7 boxes are internel and forward on to a smart host(email) in DMZ

Yes, give your E2k7 server an additional internal IP

Your Unix team will have to point their server to send to the new E2k7 IP address

If Unix can authenticate during the SMTP connection then you don't need to do any of the above because authenticated users can relay by default. Can Unix be set to authenticate?
