We need to be able to send attachments on some of our lists, but are concerned about the spread of viruses through the list server. LSoft support won't make any particular comments about what does or does not work, so I'm hoping those of you who've been doing this for a while can help me out. What kind of anti-virus setup are you using to scan messages and attachments arriving at your LISTSERV for distribution? We're running LISTSERV and LSMTP together on a WindowsNT 4.0 platform. Thank you!
