Email spam filtering

Spam doesn't just distract your employees; it can also expose your systems to malware and phishing attacks. We estimate that over 95% of all email traffic is spam. Businesses lose millions of dollars in productivity and additional infrastructure expenses due to spam. To make matters worse, organizations that maintain in-house email servers are fighting a losing battle, because spammer tactics constantly change. To defeat spam, you must stay one step ahead of the evolving threat.

Multi-layered spam filter

At Rackspace, we continuously update the spam filtering system we use for our Hosted Exchange boxes in a multi-layered process that eliminates 98% of spam—with nearly zero false positives. You get spam filtering at no additional cost with all Hosted Exchange accounts.

Layer 1: The Gateway Scan
