A zillion copies have been sent from ITESO. I know that because they are
trying to mail to some lists I have deleted recently; I got something
like 2-3 copies of the message on each list. Since LISTEARN doesn't
remove duplicates postings unless you explicitly configure your list to
do it, subscribers of LISTEARN lists got more than one copies while most
lists were unaffected. If a LISTSERV list is very active, duplicates are
possible because LISTSERV only checks the last 20 messages or so.
