MailFoundry
What is it?
Mailfoundry is a hardware appliance for Solinus, Inc. which filters email before it is delivered to your email box. Using a hardware appliance has several advantages. It allows the Doreo staff to manage all spam and anti-virus rules from a centralized location. It off-loads the spam and anti-virus filtering from the web servers (allowing them to serve your web pages faster). It provides centralized quarentine management.
How it works?
MailFoundry's MessageIQ scan engine uses a layered approach that maximizes kill rates and minimizes false positives. We do not use any 'scoring' or rating systems for identifying spam - those systems are plagued by high false positive rates and are really only 'guessing' at spam. And when it comes to protecting your message, guessing isn't good enough.
The core layer for threat identification are the spam signature files. Those spam signatures are created and managed by human spam editors who look at spam 24x7x365, and we release new spam updates every 5 minutes to ensure that our customers have the latest rule sets to defeat spam attacks as they happen.
Because our signatures are designed around actual identified spam, the system isn't guessing at identifying incoming email, thus our false positives are the lowest in the industry. Period.
What policies has Doreo implemented?
All email goes through 3 stages of filter. The first stage are realtime black lists (RBL's). These are services that provide the IP addresses of know spammers. Doreo currently utilizes the following RBL's:
The second stage is anti-virus filter and the final stage is spam filtering.
Any message that are flagged by a RBL or spam filter are placed in a quarentine. Once a day (at 01:00 am Central US time) you will receive an email if you have any new messages in the quarentin. The quarentine email contains the message subject, sender and date/time recieved. You then have the option to ignore the messages in the quarentine, view the message on-line and/or release the message. Messages are held in the quarentine for 5 days.
