We recently switched from using LISTSERV on VM to UNIX. Our lists generally are set with option SEND= Private or SEND= Owner to restrict postings to list members or owners. I'm a listserv maintainer and was just surprised to be able to post to a list with SEND= Owner, even though I'm not a Owner. This is a change from the VM version where I had to subscribe first. Is it supposed to work this way under UNIX? Is there a way to make sure that the maintainer's cannot post to lists without subscribing? Thanks, Barry
