Hello Rajesh,
Greylisting has many issues with newer smtp firewalls and spam
appliances. As they do not have much space, they usually do not retry
after receiving an error 4xx. As such we are not going to be including
greylisting in the QmailToaster.
That said, there is info on simple greylisting here:

I believe someone on this list had released a concurrency limit per ip
using tcpserver, instead of global. It will probably be a part of the
QmailToaster soon.
Thanks,
Erik

hi
nowadays once every week or so we get an enormous number of spam hits
which increases the number of concurrent incoming connections to
around 250, causing too much load on server. reducing this figure
means our clients suffer.
normally concurrency incoming it is just 25 - 40 range.
we are planning to use greylisting, searched and found quite a few
websites providing patches
a) can anybody point us to good working patch wherein we can have
grey and whitelisting of ips known servers
b) is there anybody who can share their experience using greylisting
mechanism successfully with qmail toaster, problems faced by them if
any.
