  X-Spam for Microsoft Exchange 2000/2003
  the ultimate spam exterminator for your servers and workstations  
X-Spam for Exchange 2000-2003 (X-Spam) is highly adaptive Anti-Spam Software that protects the Microsoft Exchange 2000-2003 servers from Spam. X-Spam uses advanced regular expressions and meta tests to positively identify Spam and block it.
X-Spam works at the mail protocol level and also after a mail is accepted. Thus it provides two levels of security for your email infrastructure. X-Spam uses Heuristics Scoring to reduce the probability of catching legitimate emails as Spam. These scores are generated using a special algorithm from the area of Artificial Intelligence.

Why X-Spam for Exchange 2000-2003?
X-Spam for Exchange 2000-2003 is maintenance free software and once installed will practically run itself and keep itself updated. An intuitive interface is provided to further customize the filters, scoring and other Spam fighting options. Most importantly, with its AI-based score generation, X-Spam for Exchange 2000-2003 prevents legitimate mail from being tagged as Spam.

How does X-Spam for Exchange 2000-2003 work?
X-Spam for Exchange 2000-2003 fights Spam at two levels:
  • Before accepting mail at the mail protocol layer: If a connecting mail server is listed in a Spam sending black list, mail is not accepted from it.
  • After mail has been accepted, it goes through a series of special filters that add to the total Spam score of the mail. A Spam threshold is assigned. If the mail crosses the threshold then it is tagged as Spam.
