Email Virus and Spam Protection
Email and Virus protection
is available on an account level for any domain, via the use of our Barracuda
Anti-Spam Firewall, http://www.barracudanetworks.com
The filter works on the
domain name level, i.e. all accounts in the domain must pass through the
filter, and is achieved by setting the mx record to point to
barracuda.mydomain.com for each domain. This means that all spam filtering and
virus scanning takes place on the Barracuda Spam Firewall, which preserves
resources on the mail server.
Account Level Utilization
As mail for a particular domain flows through the Spam Firewall, various virus and spam checks are made, and if the email is suspicious it is quarantined. The first time an email is quarantined for a particular user, The Barracuda Spam Firewall creates an account for that user and emails all the information necessary for accessing the quarantined email.
Below is an example:
