So I have been in the process of installing a Postfix Server on my CentOS 6.2 Virtual Private Server. I have been following this tutorial:http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-centos-6.2-x86_64Because I have never set up a Mail Server before.So everything has worked fine up until the 5th page.I am on step 15. It shows how to verify that Postfix is ready for SMTP-AUTH and TLS, but when I run the commands:telnet localhost 25and get:Trying ::1...Connected to localhost.Escape character is '^]'.220 server1.example.com ESMTP PostfixSo I type:ehlo localhostI get:250-server.cdevelop.info Hello localhost [127.0.0.1], pleased to meet you250-ENHANCEDSTATUSCODES250-PIPELINING250-8BITMIME250-SIZE250-DSN250-ETRN250-DELIVERBY250 HELPSo there is no:250-STARTTLS250-AUTH PLAIN LOGIN250-AUTH=PLAIN LOGINWhich by the guide, and common sense, shows that it isn't ready for SMTP-AUTH nor TLS.Everything has been installed in the Guide, and configured the way stated, but I am still getting this problem.What should I be looking into? either configurations, or verify packages are installed or Error logs, etc.? Is there anymore information I should provide to you folks? Or just anything else anyone would like to say about this that may help my situation. And if you can't provide any help or information, would someone mind pointing me to some good tutorials on setting up a lightweight mail server on my CentOS VPS? I really like the tutorial I am following now, because it allows Virtual Domains and Virtual Users, making it lighter, and more customizable. So if I could integrate virtual users and domains into another tutorial that would work too.
