    Besides these, you can also set some email filters via cPanel based on the subject,content etc.

    cPanel>>Email>>Email filters

    I would have to say that if you have some cash one of the BEST ways to prevent spam is to invest in a ironport enabled router, Ironport is a service that returnpath uses and filters based on the mail senders reputation, is does a GREAT job infiltering but it must either be installed on your servers network or you can install in your office network if you have a mail server there.

    These people have dropped one of my clients spam traffic almost 85% there are very FEW false positives, and the router has an integrated tool that will allow someone to recieve a return notification to be whitelisted they can follow a link and input thier information for review.

    Cisco IronPort C160 for Commercial Businesses
    they can be a little pricey, but after you have used one of these most people swear by them, new or used this is by far one of the best solutions that I have seen, yahoo, aol, and the major e-mail providers use these appliances.

    Spam is a very complex issue indeed and there is no single item you can
    do to totally block spam from your servers; However, that said there are
    many, many different things to do that each by themselves help to a
    certain extent but together prove stronger.

    First and foremost (and if you have enough memory) then I would enable
    SpamAssassin and also custom configure the rules to increase the accuracy
    and detection capability.

    Enabling RBL (Relay Block Lists) to check the IPs of the sender against
    known databases of bad IPs previously caught sending SPAM would also
    help reduce SPAM greatly. Be careful to only use the major blacklists
    such as SpamCop and related because some of the lists out there block
    all IPs or block all home user connections which would result in you
    blocking mail that could be legitimate.

    Add SPF records to all your domains in the DNS zones and update the
    DNS zone templates so that SPF records are added automatically and
    enable SPF checking on your server.

    I personally don't like domainkeys because you can lose legitimate mail
    easier but if you want to lock things down another level, you can also
    setup domainkeys checking as well.

    Disable direct access to SMTP ports from your server to just that of
    "root" or the mail service users and setup a firewall to monitor
    connection traffic.

    Run PHP as SuPHP so that you are better able to track PHP scripts
    that might be sending mail from your server and more quickly identify
    the location and owner of such scripts.

    Increase the reporting level in your advance Exim configuration (first section):
    Code:
    log_selector = +arguments +subject +received_recipients
    
    There are hundreds of other tweaks and modifications you can do to further
    lock down spam while allowing legitimate traffic but just doing the above
    will knock out the vast majority of the spam on your servers.

    Config Server And MailScanner

    Go to ConfigServer Services and check out the MailScanner product, you can download nad install it yourself or for $45 they will do it for you. How well does it work you ask?

    eximstats for today:

    Grand total summary
    -------------------
    At least one address
    TOTAL Volume Messages Addresses Edomains Delayed Failed
    Received 5160KB 293 158 0 0.0% 5 1.7%
    Delivered 1913KB 153 153 8
    Rejects 15537

    the rejects and the difference between received and delivered is due to MailScanner and Config Servers installation
