KCTC Spam and Email Virus Filtering

SPAM FILTERING - KCTC utilizes the most advanced spam protection available today. Key to KCTC's 98.2% catch rate and very low false positive count is the Sequential Content Analyzer (SCA) engine. This brand new anti-spam technology combines advanced e-mail metrics with content sampling analysis to sort and categorize spam messages without the need for counter-scripts to avoid false positives. Along with the full power of intelligent, Sieve content filtering, this unique multi-layered approach stops spammer attacks - be it brand new or just another version of last week's "get rich" scam. Sieve filtering technology is enhanced by the on-demand updating of a vast, growing network of Internet Service Providers (ISPs) who have joined forces to fight spam - so you don't have to.

QUICK FACT: Did you know that the KCTC mail server blocks over 23,000 spam messages in a 24 hour period? That's over 8 million per year - and growing.

EMAIL VIRUS FILTERING - 40,418 viruses stopped dead in their tracks... Kalona Cooperative Telephone Company's integrated anti-virus engine is powered by Norman Data Defense Systems which consistently rates as one of the top award-winning developers in the detection and removal of viruses. KCTC email and KCTC WebMail both utilize this fast scan engine to quickly and accurately identify new viruses, including any low to high risk viruses such as Goner, Badtrans, Nimda, Sircam, and MyDoom. Our servers are configured to automatically retrieve all definition updates for existing and emerging viruses. Only email processed by KCTC is checked for viruses. Email downloaded from other services, such as HotMail, Yahoo, and Juno is not checked.
