    Change your browser colors, you'll see it's explained there:

    This SMTP tweak will prevent users from bypassing the mail server to send mail (This is a common practice used by spammers). It will only allow the MTA (mail transport agent), mailman, and root to connect to remote SMTP servers.

    I think you can configure it so it will use /usr/sbin/sendmail (i.e., Exim) to send mail.

    Really? Let me check that out....

    <edit>
    Yep. Worked like a charm. If I use this setting, will there be tons of complaints from legitimate customers?

    It appears it puts iptables rules in place to check the sending processes owner.

    Would this prevent scripts like phpbb and others from sending out emails ?

    Yes if you configure them to send mail via smtp. Nobody can make smtp connections except for root.

    Wait... I don't get it. If I enable SMTP Tweak, that means "Connections to localhost on port 25 are allowed". Should I enable or disable it then?

    Here is what I found from testing it out....

    You can send email to accounts on that server ONLY!

    Using Outlook Express, if you send from server@domain.com (account on that server) to someone@another_server.com
    the email will never get to the other server.

    Basically, as I see it, it only allows "local" delivery of emails. You can not send an email from your server to another server.

    What good is it??????

    Probably your user or yourself needs to use your ISPs SMTP for outgoing mail.

    A lot of broadband providers now won't allow you to use other SMTP other than their own anyway..
