Yeah, but the original greylist whitepaper recommends against 
whitelisting email addresses or domains, as they're easily forged.  I'm 
also not fond of adding the complexity of allowing for module-specific 
whitelists.  People will do it anyway, so I integrated his extra scripts 
rather than tear that feature out.

I actually rather like the idea of an auto-whitelist that operates on 
sender/recipient pairs.  I'll probably write one up.

As it is, currently, you wouldn't.  Modules can't safely modify each 
others' DBM files.  If you wanted to go down that path, you'd want to 
add functions to the greylist module that added the addresses, and then 
import "greylist" from the auto-whitelist module.  It wouldn't be 
terrible, but I think a generic auto-whitelist could operate on its own, 
and wouldn't need those changes.

You'd want the auto-whitelist to come before whitelist_auth, so that 
whitelist_auth doesn't prevent the auto-whitelist from operating.

I say... I'll try to put out an auto-whitelist module tomorrow or the 
next day, and start documentation for use scenarios after that.
