Greylisting should only be configured to kick in when you receive something
that's almost certainly spam.
The implementation that comes with SA-Exim therefore does not have any
whitelisting support built in, however it's easy to add one anyway with
1) You write an SA rule that counteracts/disables the SA rule that helps
   with greylisting
2) You add a quick hack to
   /usr/share/perl5/Mail/SpamAssassin/Plugin/Greylisting.pm

Note however that:
1) you can greylist gmail just like everyone else. I do (and I work for
   google)
2) it's hard to get an up to date list of all sending IPs for big providers.
   Those can change at any time
