I have a dedicated and want to eliminate spam for ALL my domains

* To further reduce spam as well as other attackers, we can firewall your SMTP port to only listen to our antispam servers

    This will reject those messages that were directed around the antispam service
      + ..this would be why some spam occasionally gets through even with the antispam service enabled


    In doing so, the remainder of the spam sent to you by the spammers sending direct to your server is stopped cold!

    We can provide instructions to you for your end users so they don't get blocked when they send through your server

    We would accomplish this through the use of an alternate SMTP port, ie., port 2525 instead of 25

* Please contact NetSonic for more information and one-time charges
