Would it be possible to change this behaviour so that the whitelisting is done as soon as the same sender/receiver pair is seen again, ignoring the ip address? This could speed up things a bit.

Here is why that idea won't work, using a current output of an address which gets a lot of spam (changed domain, obviously):

GREY:24.166.74.197:<[EMAIL PROTECTED]>:<[EMAIL

You'll see that whoever runs that botnet is using the same From/To for their spam. spamd would be completely ineffectual if it ignored source IP.

I spent several weeks massaging spamd for problems with mailer pools and clueless MTA like Lotus Notes and Symantec AV gateways. It takes work, just like anything else.
