Indeed. These open relay blacklist sites were always a highly questionable source for mail filtering. Quite obviously, open relays have no relationship to spam, so using an open relay blacklist is going to block a lot of non-spam email. This wasn't the only way they duped and misled their victims. Frequently they told people to configure spam filters so that relay use (open or closed) would fool their filters. So their users got _more_ spam, not less. --Dean On Sat, 13 Sep 2003, Harald Tveit Alvestrand wrote: > I followed some links today, and discovered to my horror that one of the > spamtools I'd been using had been throwing away some valid messages - > including some from this very list. > > It turned out that OSIRUSOFT had gone belly-up, and started declaring that > "the world consists of spammers"..... or something. > > Digging into the facts gave me the following link: > > <http://news.spamassassin.org/modules.php?op=modload&name=News&file=article > &sid=44&mode=thread&order=0&thold=0> > > and the short fix is this (for people who know how to manipulate > SpamAssassin scores): > > score RCVD_IN_OSIRUSOFT_COM 0 > score X_OSIRU_DUL 0 > score X_OSIRU_DUL_FH 0 > score X_OSIRU_OPEN_RELAY 0 > score X_OSIRU_SPAM_SRC 0 > score X_OSIRU_SPAMWARE_SITE 0 > > Shows the risks of depending on too many services you don't track the > status of..... > > Harald > > >
