Dear Mailing List: I own a confidential list which has subscribers from various nets reached via gateways (Austrian X400, TU Vienna local net). The adresses used to send mail to those people remain relatively constant and contain no explicit gateways, they cause no troubles. However, the adresses in the From: fields of mails from them to Listserv change almost weekly: Gateways are changed, network naming regulations change, routing tables seem to vary from day to day, some people (especially those in computing centres) switch to another primary machine (with different OS and different userids on a different net) every second day or own and use many different userids... All this, of course, causes them to be no longer recognized as "private" by Listserv, and almost everything in connection with my list is restricted to private for good reasons. I am getting bored of changing their addresses (we are "by owner" and "validate all") every second moment, especially because the old addresses still work fine in the other direction, in spite of the changes (moreover, most of these From: adresses tend to fail in the other direction...) Any advices??? Some ideas: * Is it possible to have some kind of pattern matching when checking the identity of From: and the list members? * Is it possible to strip any explicit gateways and replace the % by @? This would already solve many cases... * Is it possible to have an alias database in Listserv? The list would contain the primary address to send list mail to, and the alias file would contain (for each primary address) all acceptable source addresses for 'private'. This would: + be most flexible + reduce the need to add/delete/change the primary addresses Perhaps there could even be commands which allow users to update their aliases by themselves (which I would enjoy very much). However, this introduces perhaps a new source of insecurities... Any comments???
