Today, after £100,000 investment and 12 months in development NDO launch their NEWT Anti-Spam and Anti-Virus Protection System.
What's NEWT? it stands for "NDO Email Without Trash" (cool huh?) and NDO claim it's 85-90% accurate against spam and virus removal is 100% effective.

The NDO customer has complete control over the strength of the spam filter and can also choose how the system handles spam emails. Suspect emails can be automatically transferred to a special "Spam Folder" within the Inbox stored on the NDO servers for checking (using the NDO webmail facility) without the need to download them to the customers local machine. NEWT also includes user defined white-lists and safe email addresses. Customers using SMTP delivery will receive their mail marked as Spam for local sorting.
