Lately we have been having an increasing problem with people not being able to subscribe because they never receive the confimation messages, so they can't confirm. Once we manually ADD them they receive the list mail just fine, but they still don't receive any job outputs from LISTSERV, regardless of what it is they do, or try to do. I figure it is some sort of deliberate block at their sites, but what would that be which allows the list distributed mail to go through, but blocks all LISTSERV job output type items? A filter for LISTSERV@* perhaps? What should I ask postmasters, or ask the subscribers to ask their postmasters, to do to allow the LISTSERV job outputs through? There are a lot of things these folk can't do if they can't receive the job outputs, which includes all "confirm" messages. Douglas Winship [log in to unmask]
