Introduction
------------

These release notes describe the installation of MailMonitor for SMTP (Windows
NT/2000). For information on how to use the product please consult the User
Manual. This document is supplied in PDF format and is available for download
from the Sophos website at http://www.sophos.com/support/docs/#smtp


New in this version
-------------------

This release includes the following new features:

* Improved scanning of malformed mail messages

* Options to perform multiple scans of emails for additional security. These
  options are 'double_scan' and 'mime_rescanning' in the [scanning] section of
  the configuration file. See the MailMonitor for SMTP user manual before
  enabling this feature.

* Fix for a reported error in the process by which the contents of the log
  file are archived each time the file is full.


Installing MailMonitor for SMTP
-------------------------------

MailMonitor for SMTP requires SAV Interface, which is provided by Sophos Anti-
Virus for Windows NT/2000. Please install Sophos Anti-Virus for Windows
NT/2000 on the server before attempting the installation of MailMonitor for
SMTP.

Once Sophos Anti-Virus for Windows NT/2000 is installed, run the MailMonitor
for SMTP setup program and follow the on-screen instructions.

NOTE: The SMTP components must be installed under a Windows NT/2000 user
      account with administrative rights.

After installation, you must ensure that:

  * Access control (access database) is enabled and configured if you wish to
    use MailMonitor access control. The user manual contains instructions for
    configuring access control. (By default, access control is disabled).

    NOTE: Alternatively, MailMonitor may be placed behind a gateway SMTP
          server, with the gateway server configured to provide the necessary
          level of protection. MailMonitor can then be set to accept mail only
          from the gateway server and pass processed mail onto a delivery
          server for transmission to recipients. This access control scheme is
          recommended should you require a greater level of protection against
          3rd party mailers than can be provided by MailMonitor.

  * Mail is directed to the scanner server, i.e. the machine where MailMonitor
    for SMTP is running, rather than to the SMTP mail server.

  * Security settings are modified so that only the MailMonitor for SMTP can
    access the SMTP server port.
