Rockliffe Ships MailSite version 6

Features Next-Generation Spam Filtering

Campbell, CA - August 15, 2003 - Rockliffe, Inc., a leading developer of email infrastructure software solutions, today announced the immediate availability of MailSite version 6 for service providers, enterprises and small/medium businesses. MailSite 6 features an anti-spam engine to block spam at the server, before it gets to the recipient. The spam scan engine is tightly integrated with improved Sieve filters at the system, domain and user levels. MailSite Spam Filter uses a unique “cocktail” approach of spam fighting technologies to block spam while avoiding false positives. MailSite Spam Filter uses heuristic analysis, pattern matching, spam definitions, white lists and black lists.

MailSite includes the ability to protect corporate data, further reduce spam by detecting directory harvest attacks and automatically dropping the harvester’s connection and blacklisting the IP address for a configurable period of time. Spammers use directory harvest attacks to steal corporate directories. Then use the information to make their spam attacks easier for themselves and more costly to recipients. In addition to the obvious spam problem, directory harvest attacks can cause performance degradation issues while the harvesting action is in progress. MailSite detects these attacks, automatically drops inbound harvest connections, and then denies future connections to the sender, thus safeguarding sensitive corporate data.

MailSite’s anti-virus filters are faster and more efficient than ever, for increased message throughput. MailSite’s improved IMAP performance is up to five times faster than previous versions, which means faster message access for the end-user. Fewer MailSite servers are required to handle the same number of users, which translates to easier administration and lower total cost of ownership
