Greetings,

I'm curious to know if anyone here has implemented greylisting with
Postfix in such a way that there is a common greylisting DB (for the
triplets) that all of the Postfix servers can utilize. Is there a
fast, reliable way to maintain only one database so that greylisted
hosts are known by all mail servers in a given configuration? What of
redundancy on the greylisting DB? What of failover if the greylisting
DB is unavailable for some reason?

I've been doing some digging on this and haven't found anything
definitive. How-to's and implementation experiences definitely
welcome.

Thanks,

Patrick

I haven't implemented grey-listing yet, but
did you take a look at
