 MAIL 

GATEWAY 5.5 

®

 Mail Gateway 5.5 is designed to filter SMTP mail traffic protecting 

mail system users from viruses and unwanted messages (spam). The application 
is a full-featured mail relay (compliant with IETF RFC internet standards) that 
runs under Linux and FreeBSD operating systems. 
The application allows the user to: 

•  Check email messages for presence of spam signs, including attached 

objects and message bodies. 

•  Use the technology of DNS black lists (RBL) to filter spam. 
•  Create white lists and black lists of senders/recipients for use by the 

application while processing email traffic. 

•  Scan email messages for viruses, including attached objects and 

message bodies. 

•  Detect infected, suspicious, corrupted, and password-protected 

attachments and message bodies. 

•  Perform anti-virus processing (including disinfection) of infected objects 

revealed in email messages by scanning. 

•  Provide additional email traffic filtering by names and MIME types of 

attachments and apply certain processing rules to the filtered objects. 

•  Maintain archives of all email messages sent and/or received by the 

application, if this is required by the internal security policy of the 
company. 

•  Enable restrictions for SMTP connections providing protection against 

hacking attacks and preventing application use as an open mail relay for 
unsolicited email messages. 

•  Limit the load on your server by configuring the application settings and 

SMTP parameters. 

•  Notify senders, recipients, and the administrator about messages 

containing infected, suspicious, or corrupted objects. 

•  Quarantine messages identified as spam or probable spam as well as 

messages containing infected, suspicious or corrupted objects. 

•  Update the anti-virus and content filtration databases. The application 

retrieves updates from the update servers of Kaspersky Lab. You can 
also set the application up to update the databases from a local directory.
