    I have linux box with WHM 11.32.3 (build 21)
    CENTOS 5.8 x86_64 xenhvm on server2

    I have set in: Main >> Security Center >> SMTP Tweak
    The SMTP Tweak is enabled.

    But steel having remote attempts to send mail using my server.
    Example log entry below:

    Result: JunkMail rejected - []:12617 is in an RBL, see The Spamhaus Project - Blocklist Removal Center Results

    How can I completely block remote SMTP mail devivery using my server? I can`t completely block SMTP because It is used in my PHP applications on server which are not sending junk mail.
