for SMTP

Also available as an Adobe Acrobat PDF file smtp.pdf ( 54k).

MailMonitor for SMTP detects, reports and disinfects viruses in email sent via an SMTP (Simple Mail Transfer Protocol) server. A threat reduction module* also allows users to block potential virus carriers at the gateway. MailMonitor is installed on sites which have an SMTP mail server, an SMTP mail server and an email server, or an email server only. Infected attachments are quarantined, replaced or automatically disinfected before delivery to the recipient. Comprehensive messaging allows MailMonitor to notify administrators, senders and recipients of any viruses found. MailMonitor for SMTP can find viruses in attachments compressed with ZIP and other popular compression utilities.

Virus detection and disinfection is performed by the high-speed Sophos virus engine, which allows easy, central and transparent updating of virus definitions.

How it works

Sophos MailMonitor for SMTP uses SAVI (Sophos Anti-Virus Interface), which is included on the Sophos CD as part of the MailMonitor installation.

Once installed, MailMonitor operates in real-time mode. It intercepts and scans incoming and outgoing email attachments to and from an SMTP server as they are sent or received. If messages are found to be virus-free, they are passed on to the mail server.

Infected attachments are disinfected, deleted or quarantined. The administrator has full control over quarantined attachments.

The threat reduction module* allows MailMonitor optionally to block:

• file types by file extension and/or filename
• Windows and DOS executables even if the extension has been changed to mask the file's real identity
• all messages with a specific subject line
• all mass mailings sent to more than a specified number of recipients.
