On my environment, I have a UNIX PC in the DMZ and all I have on it is a SMTP service with one mailbox. The role of this PC is to collect mails arriving to @mydomain.com. My UNIX cannot push mails to the Exchange Server inside the LAN. In the LAN, I have an Exchange server that goes every minute to collect mails from the UNIX with POPBEAMER. You have to configure your firewall to translate the External IP address to the Exchange IP Address. If you need any further assistance - we are here.

First and foremost we dont plan to implement a front end back end scenairio Secondly the exchange box sits behind the firewall and is secured, Thirdly it is only the unix box that hosts the smtp service that sits in front of the firewall. Since the exchange box is in high use the idea is to take the load of processing smtp traffic off the exchange server and move it to the unix box, so in essence, all traffic bound for outside the local domain will be forwarded to the unix box, and when the unix box receives any email it forwards it to the exchange box for final delivery. Thanks, i guess you get a clearer picture now cheers >From: "John Tolmachoff (Lists)" <johnlist@xxxxxxxxxxxxxxxxxxx> >Reply-To: "[ExchangeList]" <exchangelist@xxxxxxxxxxxxx> >To: "[ExchangeList]" <exchangelist@xxxxxxxxxxxxx> >Subject: [exchangelist] RE: Relocation of SMTP Service to a UNIX box >Date: Wed, 19 Jan 2005 02:52:05 -0800 > >http://www.MSExchange.org/ > >1.
