Hello! I want to establish the following systems: A first firewall is set up to protect the DMZ and the internal LAN from the WEB A second firewall including an E-Mail-Filter and Proxies protects the LAN from the DMZ. My domain host can only deliver E-Mails if I request them with POP3. The E-Mail-Filter needs E-Mails send by SMTP. So I want to place a Linux-Box in the DMZ that gets all E-Mail from two providers and delivers them directly to the SMTP-Filtersystem on the 2nd firewall. This is thought to check for Virus, Spam etc and to send the filtered E-Mail to the internal Server. My problem: I do not have any idea on how to configure the Linux box in the DMZ to automatically poll the E-Mail by POP3, approx all 10 Minutes and to send this directly to the Filter-System. It needs to send ALL received E-Mail to the filter. Sadly I don´t have much time to do research on this and that´s why I ask you for help: Does anybody have a sample configuration for me or can tell me the source of a documentation on the web? Thank you for your answers, passed to ingo@doerrie-net.de in advance. Have a nice Easter Time! Greetz, Ingo
