Not receiving Anti Spam updates If you are not receiving anti spam updates from the MailSite and have paid for an update subscription, please check your firewall settings. In order to receive updates from the update server and you have a firewall, make sure you:

• Permit FTP (TCP) connections to/from vu.rockliffe.com (IP 216.34.131.7)
• Permit HTTP (TCP) Connections to/from sn34.mailshell.net

The Anti Spam engine will download .dll files amongst others. You should ensure your Firewall permits the download of these types of files to the server.

MailSite was designed to use Active FTP connections. If the system has problems using Active FTP, it will revert to Passive FTP automatically.
