In addition, LISTSERV 1.8e is the first and so far the only e-mail list management software in the industry to provide e-mail lists with virus protection. The integrated F-Secure Anti-Virus system scans every message and attachment posted to a mailing list for viruses. If a virus is detected, the message is automatically rejected. F-Secure Anti-Virus is engineered for fast, automatic virus database updates and uses multiple scanning engines, providing LISTSERV lists with the best possible virus protection.
