During last days I have noticed an increasing of 'rejected' messages. I'm currently using 'zen.spamhaus.org' and 'list.dsbl.org' as reputation servers.
At the same time, the number of false negative is growth. I would like to know if is there any better reputation server that anyone know (of course, it would be nice if it is a free service :-)). Anyway I heard talking about URIBL, which as I have understod is a quite different service (it blacklists 'domains' rather 'IPs'). But is it maybe a dangerous practice to fight spam? Anyway, does anyone suggest me to use URIBL? Thanks, rocsca
