    1. I followed And I doubt that whether information when postfix SMTP is authenticating is encrypted or not?

    2. Can I follow Postfix-SMTP-AUTH-TLS-HOWTO instead of above URL in only installing postfix section?

    3. 250-XVERP means? ( it is the difference between setup at Postfix-SMTP-AUTH-TLS-HOWTO and The Perfect Setup - Fedora Core 4 )

    4. I already completed ISPConfig installation, can I do adding smtpd_sender_restrictions = permit_mynetworks,
    smtpd_sender_login_maps = hash:/usr/local/etc/postfix/sender_login_maps

    to ???

    5. Every time I restart server, do I have to start some services? or leave the machine as it is.

    Thank you very much. :)

    Normally we use PLAIN and LOGIN authentication (so that also MS email clients can use the mail server... ;) ) which means the authentication happens unencrypted. When you run
    telnet localhost 25
    you can see which authentication mechanisms your server offers.

    Yes, you can, but then you have to compile Postfix and the other packages yourself which means you cannot use your distribution's package manager (on FC it's yum) anymore to update these packages. If you don't want to use yum, then compiling packages is no problem.

    I think so...

    Normally the services should start at boot time. If they don't, run
    chkconfig --levels 235 <name of init script> on
    Then the service will start at boot time. Replace
    <name of init script> with the name of the service's init script in /etc/init.d.
