Please note that this feature is not available under LISTSERV Lite.

Please note that the anti-virus scanning software is available only for Windows Server versions currently supported by L-Soft, and that this feature is only available for LISTSERV Classic or LISTSERV Classic HPO sites running those operating systems.  An L-Soft maintenance contract is also required.

LISTSERV Version 17.5 supports on-the-fly anti-virus scanning of all messages sent to mailing lists that run under LISTSERV Classic or LISTSERV Classic HPO on Windows, including inline uuencoded binaries and MIME attachments in those messages.  This is a value-added feature which, in addition to a regularly-licensed LISTSERV Classic or LISTSERV Classic-HPO installation, requires a paid-up LISTSERV maintenance contract with L-Soft.  (Please contact your sales representative if you have questions regarding the maintenance contract.)

In order to use LISTSERV®’s Anti-Virus features, you must have Microsoft Windows Defender (or a third-party anti-virus program; see below if this is the case) installed on the LISTSERV machine.

If you are already running a different Windows anti-virus product in your enterprise, it should be possible to install your existing anti-virus product on your server and then use it with LISTSERV by adding the site-level configuration setting:

FOREIGN_ANTI_VIRUS=1

The setting can be made either by adding the string shown above to LISTSERV's \MAIN\SITE.CFG file, or via the web interface under Server Administration/Site Configuration/Anti-Virus and then setting the value for FOREIGN_ANTI_VIRUS to "Yes (1)" in the dropdown list box. In either case, the server must be restarted to pick up the change.
