I keep them for two days.

I use 40 days.

I don't whitelist the IP address, but once an IP has retried, I don't
greylist it again for 40 days.

For the original tuple, I use <sender,recip,classC> where classC is the
IP's /24 network. For whitelisting a host-known-to-retry, I use the
entire IP address.
