Simple E-Mail Routing Alternatives
A. Unprotected E-Mail Routing
Unrestricted e-mail transfers between the mail server and the web. The mail server is an easy target for open relaying by spammers. It can also fall victim to dangerous HTML content and as-yet unknown viruses.
Analysis: Dangerously ill-advised method for messaging.
B. Message Routing with trimMail Inbox
- Inbound SMTP mail goes to trimMail Inbox, where it is tagged for spam and cleansed of scripts and other potentially dangerous contents. By transferring only those messages destined for the specified mail server, trimMail Inbox prevents spammers from using the mail server as an open relay.
- The mail server then collects all mail destined for its e-mail clients from trimMail Inbox.
- Outbound e-mail is routed directly from the mail server to the Internet.
Analysis: Primary mail server is isolated from specific Denial of Service attacks, dangerous HTML contents and open relaying by spammers. End users are relieved of mountains of spam and dangerous HTML contents.
