    Not quite sure if I understand you correctly, you want to configure your server so that everyone can use it to send emails trough your server or in other words you want to create a open relay server? Such servers will be misused for spamming within a few hours and then your IP address gets blocked by all major blacklists so none of your emails will arrive anymore. For that reasons all mail servers in the internet are password protected like your current setup is, you can send from your server to any domain and IP you want and you can connect from any IP after you authenticated yourself on the server with smtp-auth. Take a look at your email program, you just have to enable that.

    Poor idea:

    - your server will be killed in minutes/hours
    - your domain will be listed in spam botnets "forever"
    - I don't know where you are but probably you will be in troubles with the justice
    - You will send tons of illegal stuff every second.

    We fight spam/abuse here. This is just a criminal idea

    I was useing qmail for 7 years and now indimail for 1 year and im not black listed. I only allow 1 /19 class to access the smtp server i will not use it for the whole world i have blocked everything else with firewall. Im trying to switch to ispconfig but i cant make it work with sending mail from other domains.
    Will u help me or not?
    Im not doing anything illegal. I just try to let my users to be able to send mail.
    I have newer had problems with qmail or indimail, and im using them as open relay.
    Ill ask again.

    Yes it can be done.

    In your set "smtpd_recipient_restrictions = permit" and "smtpd_delay_reject = yes".

    Restart postfix.. Say your prayer, and good luck!

    Looking forward to your next post about your mail not beeing received by other providers.
