I am totally new to sendmail and I have couple questions on that:
1. I am trying the sendmail on my Redhat Linux 6.1. I use rpm to install it. It is working ok so far for me. I mean I can send and recieve email from that local linux computer. However, when I want to use Netscape,as MUA, of another Windows 98 machine to read my email from that Linux machine, it just don't work for me! I wonder there are some config file I need to change in the sendmail before I can do the remote mail retrival. Is anyone can show me how to do that step by step?
2. I have another question on the SMTP daemon. I know the smtp daemon is running on my linux server. I tried to use this smtp daemon in my linux server to send email. It works without asking me for any password for that! I'm worry about the security issue. In that case, anyone can use my server to send mail as long as they know I have sendmail install on my linux, right? Is that anything I can do to set it just for specfic range of my domain to send email by using the smtp server?
3. I read some linux books for sendmail. Most of them said "sendmail" is not easy to admin and config. What is your opinion on that? They recommand "Smail" for beginner instead. Is that really the case? Those book I read is quite old. I wonder if that is still the case for Redhat Linux 6.1?
I know I have too much question for you. But I will more than apprciate, if you can help me to solve my problem on sendmail.
