I wouldn't suggest it. I've not researched all of the blacklisting services...but some of them are what I would call "hostile" or "xenophobic". Besides, there is a certain level of overhead associated with using these. If I were to implement, I would use a milter instead of the builtin sendmail feature. Most milters allow for whitelists and other niceties. > I actually find SpamAssassin by itself is quite adequate, > reducing spam to perhaps 5% of my email. > But if adding SpamHaus improves even this > I am more than willing to try it. > > IMHO, it isn't worth the effort. A while back I did some observations and found that greylisting was most effective at cutting spam. By itself, it cut spam by 90% or more. So, I only use greylisting + spamassassin. -- Fry: That's it! You can only take my money for so long before you take it all and I say enough! 葛斯克 愛德華 / 台北市八德路四段
