I have a number of lists that I would like to restrict to this institution (my "institution" is UVVM and any other system in the UVic.CA Domain). I have used the following relevant keywords: * Local= UVVM,*.UVIC.CA Service= Local * Review= Service Send= Service Confidential= Service This seems (almost) to have the desired result, except that mail from, for example "Sol.UVic.CA" is rejected. By changing the "Send" parameter to "public" seems to work fine and, because the list is confidential outside UVic, should not result in postings from outside. Have I defined something wrong, missed something obvious, or is this a bug with the Send parameter?
