FWIW, grey listing has cut incoming spam here by 80%.

What sort of time delay do you find it adds to getting your mail?

None. The greylist milter has a cache. The very first time a system contacts mine there will be a 5 minute delay. After that....0.

Almost! ;-)

When a mail comes in, it checks the triplet client_ip/sender/recipient to see if a mail has been sent before with that triplet. If it has, the mail passes OK. If not, mail is bounced with a termporary error (this tells the clients mail server to try again in 5 minutes), and the triplet it temporarly saved. In five minutes the same mail gets sent again and the server accepts it. :-)

Nope, not have any problems your seeing. Must be a Souther Hemisphere thingy.

Naahhh. :-D
