Hello, I know this has been asked several hundred times here but this Newbie needs some advice. I have spent the past couple days on here printing and reading the How to Tutorials and I cannot seem to make up my mind on what tutorial and distro I want to use. I have basic linux experience. Here at the office we have 2 servers. Both servers are currently running Windows 2003 SMB Server. Server 1 hosts our 4 websites. Server 2 (the server in question) is again Windows 2003 SMB Server which has Vircom Modus Mail running for Email Services POP3 and SMTP. We have 4 virtual mail domains running off 1 public ip address. All this has been working fine for the past 2 years. The problem is SPAM, I would like to build a linux box to act as a SPAM filtering gateway which will filter the email and forward that onto our Windows 2003 SMB mail server. My question is can this done and what tutorial would you recommend? I contacted our Internet Provider who will be giving me another public ip address to use for this box which will be behind our internal firewall (Sonicwall). Also, our Internet Provider does our DNS hosting for us. I would appreciate any help you can give me. Thank you.
