Hosted Exchange Spam Filtering

Unfortunately, spam email is a fact of life, an ongoing problem that ranges from harmless marketing messages, to malicious emails, intended to infect the recipient with malware, or to attempt to scam them in some way. All hosted exchange providers provide tools for managing spam.

Spam filtering is a must have feature of every email host. Microsoft Exchange server provides both server side spam filtering (meaning that spam is intercepted as it is delivered to the server and before it appears in a user’s mailbox), and also client side spam filtering tools.

One of the main spam filtering features of Microsoft Exchange is the use of blacklists and whitelists. Individual mailbox users can configure these lists from within Microsoft Outlook. This allows users to allow mail through that has previously been marked as spam or tag individual email addresses (or entire domains) as spam. These flagged address or domains will be added to the spam filtering rules run by the Microsoft Exchange host.

This combination of server side spam filtering, and client side tools for tweaking spam filtering rules, makes the combination of Microsoft Exchange server and Microsoft Outlook, one of the most effective spam filtering engines available.

Advanced users of hosted Exchange server, can also edit the spam filtering rules directly on the server, changing spam filtering for all users. This is especially useful for companies that want to make sure the entire organization has standardized spam filtering rules that can be easily updated and modified.
