Hi, I'm trying to stop someone from subscribing and posting to a list. It looks like I need to use the filter command in my header. Before I do it can someone confirm that * filter= Also,[log in to unmask] Will do the trick? I'm including the pertinant documentation from L-Soft below. I was a little confused by the safe stuff. The way I understand it, if I use also, it will run the standard listserv filter. It doesn't require the listserv maintainers approval, right? Thanks josh harmon >------------------------------------------- >Filter= Only | Also | Safe,net-address1,net-address2,.... >"Filter=" is checked when a user attempts to post or subscribe to a list (but >not when the list owner issues an ADD command).
