Greetings, We are running Listserv on IRIX (unix) 1.8b. On July 19th we went live with our firewall. Since then (starting on July 20th) we started receiving a few complaints from people because they were receiving mail from Listserv Lists that they had never heard of and certainly never subscribed to before. The numbers have now grown from a few to 35+...including one of our staff members. I checked the headers of the mail coming in to our staff member from about 8 separate lists. They all seem to come from "[log in to unmask]" via Buffalo, which is our closest listserv neighbour. There was no indication of someone bouncing the mail or forwarding the mail....etc. The individuals were not subscribed to any of the lists in that no one has ever received a "You are now subscribed to" message. I did a 'review' of about 8 of the lists (there are about 18 or more lists altogether) and the person is not subscribed, yet continues to get mail. What I did notice from the 'review listname' is that there is at least one subscriber from our site subscribed...but I haven't had time to check all of them. Is it possible that this is due to our installation of our firewall? I read the latest version of the listowner's guide as an indication as to how Listserv might respond to such an event, but it just doesn't seem to make sense....and given the numbers, it also doesn't make sense that these are all bogus mails...there are just too many of them. The Admin of the firewall was also given a copy of the relevant section of the guide and what was stated was taken into account. This is truly a mystery for us and a source of agrivation for those subscribed to Listserv lists....and they are also under limitations of mail spool space....some have up to 50 mails a day.....sigh...and we have a mail limit of 1.5MB (at which point we delete mail based on date). Any info (including guesses) would be appreciated.... I'm pretty desperate as this appears to be random with the exception that all of the people this has happened to do sub to one or more lists....though not quite accurate as I haven't had this problem and I am sub'd to about 4 listserv lists. Any insight much appreciated... (read: HELP! :-)) --Trish ------ Trish Forrest Computing Services, University of Windsor, Postmaster
