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!  :-))
