    I have followed the Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)
    I don't have reverse dns, so i want to relay all my e-mail with gmail.
    How to enable STARTTLS in postfix??

    Does gmail allow relaying ? How do u plan to do this ? I think the howto enables STARTTLS by default.

    Okay in that case postfix does support postfix as a client authentication.

    Add this to your config
     smtp_sasl_auth_enable = yes
     smtp_sasl_password_maps = hash:/etc/postfix/gmail_passwd
     smtp_sasl_type = cyrus
     relayhost = []:587
    Create the file /etc/postfix/gmail_passwd
    []:587            [email protected]:password
    postmap /etc/postfix/gmail_passwd
    postfix restart
