Is it that good if it doesn't even support the basic things like rbl
testing and greylisting?
Furthermore, the only spamfilter that has zero false positives is a
disabled spamfilter, even humans make mistakes. And if you use rbls and
greylisting, how can you be sure you will still have the alleged 0 false
positives?
Furthermore, exim supports scanning with Kaspersky.
