[Greylist-users] Whitelisting

I've been testing my own greylist implementation for a couple of days 
now and noticed that there still is some work to be done in whitelisting 
sending servers that just won't try again (within a reasonable time).
I started by grabbing the withelist from 
http://greylisting.org/whitelisting.shtml but soon had to add some more.

- In my test hotmail.com wouldn't try again (it instantly sends back an 
error e-mail to the sender). While I do use an error 451.
- Also mail2web.com doesn't seem to try again.
- Mails sent from iMode.be or iMode.nl are sent twice within the same 
minute, but aren't tried again after that.
- It even seems that this mailing list about greylisting doesn't try again.

If anyone knows other addresses that I should add, please let me know.

Does anyone maintain an up-to-date whitelist. Maybe even one that can be 
updated automatically via rsync or something like that? It certainly 
would be a handy addition.
