Utilizing the latest technology in spam detection Spam Firewalls are fast becoming useful to businesses of all sizes both large and small.

Spam Firewalls (Spamwalls) detect and filter emails that are determined to be spam for users.

Additionally, these units can be used as a backup MX device to store email in the event that the customers office is offline for any period of time.

By colocating these devices in a facility that is online 24 hours a day 7 days a week, you can provide your office with an additional precaution in the event of an outage.

ExpressColo has several Barracuda SpamWall servers colocated in our rack space. Several customers use a SpamWall server at their office location, and then cluster that SpamWall with a second SpamWall colocated at our location. This setup provides a fully redundant, spam filtering option as well as a disaster recovery option should their office be knocked offline for any reason.
