Background: The major flaw and immediate cause of most virus or worm email infections is that when message is downloaded by email client - it is already TOO LATE. Malicious code executes before anything can be done to prevent it - so the harm is already done. Mailbox Guard offers a better way. It lets the user see all incoming mail right on the server, and remove unwanted or suspicious messages right there. But not only. It scans and analyzes on the fly every message and rank its risk in four categories:
- Virus - active malware; viruses, worms, trojans, spyware etc.
- SPAM - all kinds of unsolicited mail.
- X-rated - messages with adult only contents X and R rated.
- Bad Language - messages with foul, obscene, explicit language.

Results are presented as a simple color-coded tags (Risk-Level Mapping):
3 Red - clear and present danger, contains elements classified as such.
2 Orange - high, contain components that are likely harmful.
1 Yellow - medium, something looks not quite right.
0 Green - low, message appear to be "clean".
