Model: 3550
Condition: Used
Warranty: 90

Whereas the majority of messaging security appliances aim to thwart all spam with a single solution, the MailGate Edge concentrates on what Tumbleweed calls 'dark traffic'. This actually accounts for a large proportion of unwanted inbound communications, as it comprises areas such as DHAs (directory harvest attacks), DoS (Denial-of-Service) attacks, SMTP-related errors and malformed packets. The idea behind the Edge is to block the bulk of undesirable mail-related traffic before it enters the network, allowing servers or appliances providing mail content checking and filtering services to function more effectively.
The 1U appliance itself is unimpressive. While it provides a reasonable specification, the variable speed cooling fans are noisy and poorly controlled. With only the Edge Defense module licensed on the appliance, the web interface is minimal but easily navigable. A number of defences are already activated and include the standard file-size restrictions, which allow the appliance's MTA (mail transfer agent) to block message attachments above a certain size in megabytes. The MTA is also used to block messages with more than a specific number of recipients.
