    Hi all,

    I would like to disable outgoing SMTP for my clients. I would like them to use their ISP outgoing SMTP servers because of spamming issues.. How would I achieve this?? Oh and I am using WHM/cPanel..

    Kind Regards,
    Mini

    If you have a server-side firewall, which you probably do, the easiest way would be to block access to port 25, or whichever port you use for SMTP.

    This way external clients would not be able to connect to send mail without preventing Perl, PHP and the like from doing so.

    IIRC, that's the purpose of the WHM > Tweak Security > SMTP Tweak.

    Yep, that sounds more like it.

    My post makes somewhat no sense after I took the time to re-read the inital post and grasp the actual question being asked!

    You were right, it's just that that option does it for you by restricting (through iptables) who can connect directly to port 25 outgoing on the server.
