Using greylisting alone will be soon almost unuseful.
Maybe, but it's stopping a lot of junk for us :)
DNSBL too block a lot of spam. Which could be the difference of using
greylisting and DNSBL returning code errors "450 Service temporary
unavailable" ??.
xxx@localhost (reason: 450 Service temporarily unavailable; Client host
[206.46.170.173] temporarily blocked using bl.spamcop.net - see
http://www.spamcop.net/bl.shtml?206.46.170.173
It's a soft way to use DNSbl without collateral damage.
