I must confess something. Though I have toyed with Linux for some time, I set my main domain server up as an NT box because at least I know how to configure e-mail with it. I'm running a program out of New Zealand called DWatch that for 5 users or less, is free. I tried setting my server up running Mandrake Linux 7 and every time I tried to send e-mail to a defined user, it would give an error message back saying something to the effect of now relaying allowed. At that time, I was not trying to relay, I was merely trying to send a message to a registered user. In frustration I reinstalled NT Server and installed DWatch which is free for 5 users or less. I don't want a big domain, or anything. I registered pamarq.com just to learn more. I wanted to run Linux on it, but could not because I didn't have the know-how to set up Sendmail. My main PC is running Linux with VMWare clients of Windows applications primarily for my wife. I want my server to be running Linux too, but have not found a simple e-mail (pop3/smtp) program that is easy to configure within Linux. Here is what I want: 2 or 3 users being able to log into pamarq.com (currently I have mark@pamarq.com, mmyers@pamarq.com and pamela@pamarq.com). I also want to be able to relay within my personal domain at fastq plus one other IP address which is the firewall IP address of my company. That is it. Nothing fancy. I could figure out how to do this with DWatch for NT, but is there something simple that I could run on Linux that would do the same thing? I don't need heavy duty. I just want to prevent spammers from using my server, but in the same way, I want to be able to relay from my server while at work (my IP address for our firewall never changes). Please help if you can help me to figure out a simple solution with Linux. I'm not an absolute novice, but I don't need anything fancy either. At work I'm an NT administrator so I run a 100% Microsoft network (not my choice). I was even told today to take the Linux server off that monitored Internet usage. So I need to be able to relay from 1 IP address from the Internet, and a range of IP address (192.168.204.2*) (fictional) from home. I don't want to run a business per se, nor do I want to run an ISP. I just want to learn. Any advice would be helpful. Thanks! Mark Myers
