For an editor, I just use "vi". I'm old school like that. As far as adding e-mail accounts, that's easy. Like you said, add users to the system where the mail server is and you would be all set. To add users, just use the "useradd" command. Do a "man useradd" to get the options you want. That should take care of that. As far as a server, set up an MTA, such as Postfix or Sendmail. Then, to set up pop3 access, go to /etc/xinetd.d/ipop3 and change disabled = yes to disabled = no. Then, restart the xinetd service. If you're running RH, do this by "service xinetd restart". Hope that helps.
