MailMarshal SMTP Content Analysis
Content analysis is the heart of MailMarshal SMTP.
What's The Problem?
Every email message is different, and every organization has different requirements for email usage. Even within an organization, requirements can differ bewteen users, and new types of content can be required daily.
The dynamic nature of email poses unique challenges for the enforcement of email content security policy. Policy can describe what content is inappropriate, but not where that inappropriate content will come from.
How Can MailMarshal SMTP Help?
MailMarshal deploys a number of technologies to analyze email content and apply your policy.
- The MailMarshal Receiver tests email as it arrives from outside servers. The Receiver can reject incoming email that is malformed, or that originates from banned locations. The Receiver can also reject email based on ESMTP criteria such as message size and sender.
- The MailMarshal Engine scans messages that have been received.
- Each message is "exploded" into its component MIME parts.
- Compressed attachments are recursively exploded.
- The message is passed to Marshal's SpamCensor for analysis. SpamCensor uses a multi-dimensional approach to determine the probability that a message is Spam.
- Each part of the message is checked against the site's policy. The policy can be based on the sender, recipient, text content, file type, file name/extension, and many other variables.
- Each part of the message can be passed to an Anti-Virus scanner and an Anti-Spyware Scanner.
- Images can be scanned by Image Analyzer to determine the presence of inappropriate content.
- Based on the results of the content analysis, MailMarshal can quarantine or redirect the message, or deliver it as addressed.
MailMarshal SMTP allows you to monitor and control the flow of information through your email servers. It provides an important tool to enforce your Acceptable Use Policy for email.
