Another approach to email security is to actively manage the emails being sent and received by your organization by means of rules and policies. This methodology is possibly more suited to those companies that require detailed audit trails, or who have had a problem with the unauthorized release of proprietary information via email, and it is the methodology espoused by Futuresoft's DynaComm i:series of products.
The control of email is the responsibility of DynaComm i:mail, which is fully integrated with the other products in the suite - these include an internet traffic filter and a file content scanner. Built into a dedicated SMTP server, the product can be positioned in a number of locations, depending on the configuration of your network and the needs of your business. It can also be located within the internal network, in which case all email - inbound and outgoing - will be processed. For smaller businesses with low email use - and smaller budgets - it can be located with the email server itself.
