Industry analyst Gartner Inc. claims that up to 50% of the average business mailbox is spam! It is quickly becoming a potential legal liability and a major productivity drain for corporate IT departments and end users. To help combat the onslaught of unwanted inbound email, lost productivity, consumption of communication bandwidth, and drain of technical support, many companies have created add-in and standalone software to prevent the delivery of spam to end user mailboxes.

Spam Arrest's enterprise solution is an easy and cost-effective way for organizations to protect against unwanted spam. Using Spam Arrest protection services, all incoming email messages sent to an organization's domain are first routed to Spam Arrest's datacenter servers. Messages sent to protected accounts are processed at Spam Arrest and only messages from verified senders are forwarded to your SMTP server. Otherwise, nonprotected email is immediately forwarded to the organization's SMTP server. This solution is good for organizations looking to minimize in-house hardware needs.
