You're looking for /etc/mail/greylist.conf to which you can edit a 
section that looks like this:
# These users will be exempted from Greylisting
list "open users" rcpt {   \
         user1 at domain.tld \
         userxyz at anotherdomain.tld \
\
}
acl whitelist list "open users"

Just add the lines as you need, make sure to end a line with a \.

Not in one list, no.   But assuming you're looking to exempt a SENDER 
from greylisting, that's also in /etc/mail/greylist.conf.  You can also 
add in subnets or IPs that you want to exempt for whatever reason.

We use extensive greylisting across our webhosting systems.  We filter 
all of our BlueOnyx-bound mail through a network of centralized 
filtering systems.  I just checked our exemption list:  5 users.  <shrug>
