You shouldn't have told them you were delaying any email....
After the first message there is no further delays and my bet is that
they wouldn't have noticed anything unless you pointed it out.
I have found greylisting is quite capable of removing 50% of the spam
before I even have to process it on my servers.
If you have the horsepower for it you don't need to do this
greylisting...

Check out http://policyd.sourceforge.net/ then as it allows you to
specify Servers/IP that should not be greylisted. Works very well.

Hi,
I am setting up a new server, so have a chance to make big
changes to
my email server.
I have been thinking about implementing Greylisting. However, I am
worried about blocking/long delays with e-mails from mail farms
(gmail, yahoo etc.)
I would very much appreciate other people's recommendations on
Greylisting or other approaches to reducing the load on my server by
rejecting spam early.
I tried out greylisting for several months for a select group of users
using greylist-milter. Their unanimous opinion was that they
wanted to
receive mail "instantly". The 10 - 60 minute delay for first-time
senders was unacceptable. The reduction in spam was not noticeable
as we
get great results using a combination of ClamAV ans SpamAssassin
with a
global bayes filter and many RDJ rules.
