Not only Lotus Notes, also for ex. Kerio Mailserver.
We tried to use it.. but ended up with more failures then temporary failures.
The concept is good .. but in real i don't think it will make it !..

Aside from the other replies, watch out because older versions of Lotus Notes treat a soft fail as a hard failure. So it's not great in a corporate setting.
I tried greylisting for two months on my primary mail server. I enjoyed the (slight) reduction in spam but I also couldn't live with important emails being deferred and not tried again. This is common with financial institutions, for exactly the same reasons they stamp things like "DO NOT FORWARD" on envelopes.
So, you can try catching and whitelisting every such instance (after some poor schlep doesn't get his credit card statement) or you can choose not to use greylisting. I had to disable it.
Now, where greylisting IS appropriate and very useful is on backup MX servers.
