How MailScan 5.6 for SMTP Server works?
MailScan 5.6 for SMTP Servers
provides Virus Security, Content Security and Spam Security for your e-mail server.
It is placed in the path of SMTP traffic and all e-mails pass through MailScan
before reaching their destination. When an e-mail is received:
- It is dis-assembled into the following components:
|
 | |
|
- Body and attachments pass through the Virus-Analyzer and the
Content-Analyzer.
- Based on the results, the mail is either:
- Delivered to its destination
- Forwarded to the administrator
- Deleted
or
- Quarantined
Mail Receiver:.
MailScan has
a comprehensive SMTP receiver daemon. Termed as the SMTPD-SMTP Server, the daemon
receives mail from sender and saves it in the spool directory for further processing.
The SMTP receiver daemon is a multi-threaded module and can handle heavy e-mail
traffic.
MailScan's SMTP Server can prevent unauthorized relaying using
two techniques: - Checks validity of the Sender-Domain before accepting
an e-mail connection.
- Allows only known IP addresses to send e-mails
to the Internet.
Message Dis-assembly
The MailScan Dispatcher
splits each e-mail message into various components such as the header, body and
attachment. Compressed formats (ZIP, ARJ, etc.) are scanned for viruses and cleaned.
MailScan Content Validation: - Each attachment (including
the body, if it is in HTML format) is checked for:
- Viruses
(using the AVP Anti-Virus engine)
- Restricted Content (using the Content
Analyzer)
- Eligibility of the attachments to pass through the gateway (using
the Attachment Validation engine)
Mail Delivery - Depending
on the results of content and attachment validation, the e-mail is either:
- Sent to the destination
- Quarantined or
- Forwarded to
the Administrator
As and when required, warning messages to
the sender, the recipient and the administrators are generated. - The
e-mail is sent to its destination using a fixed routing (relay) or by using DNS
lookups.
