This virtual machine mail filter appliance is designed to give small businesses and organizations the ability to deploy spam and virus checking for their e-mail communications in only minutes. It accomplishes this by acting as a preprocessor, retrieving and scanning all incoming mail and then forwarding it to its final destination. It offers the unique benefits of allowing users to view and delete quarantined messages through a custom, easy-to-use web interface, and account integration with Microsoft Exchange and Active Directory via LDAP, if that server is also being used.
Open source and free software is used throughout, so no licensing costs
are incurred.
Because users do not access the filter directly, its deployment can be completely
transparent, and no user account details need to reside on the appliance.
This means the filter can be integrated equally well into both new and existing mail
infrastructures and is compatible with any mail system which can accept
SMTP connections (virtually any Internet-capable mail system). In addition
to traditional SMTP operation, the mail
filter can act in a "fetching" mode, where messages are retrieved from a
remote host, such as a hosting provider, which is ideal for businesses that
have their e-mail services hosted by a third-party.
