Can LISTSERV scan incoming mail for viruses or worms (or any kind of malicious attachment) before it processes mail for a list?
LISTSERV 1.8e: Yes. From the release notes: LISTSERV Version 1.8e supports real-time anti-virus scanning of all messages sent to mailing lists that run under LISTSERV Classic or LISTSERV Classic HPO on Windows NT/2000/XP and Linux servers, 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 the following: 1. For sites with perpetual (“EXP=NEVER”) LAKs: An additional “maintenance” LAK, meaning that you must purchase maintenance (which includes automatic anti-virus signature updates for the term of the LAK) for LISTSERV in order to use the feature. This LAK will come from your sales representative automatically when a perpetual LISTSERV LAK is purchased with maintenance and must be renewed yearly. 2. For all sites: A separate F-Secure Anti-Virus key that should be sent to you by your sales representative along with your LISTSERV
