greylistd whitelist entries typically take the form of:
<incoming IP address> <sending email addr> <recipient email addr>
but when you have email outbound on your server, you'll only have two of
these. In theory you could write an ACL rule that when an email is being sent
outbound by one of your users that outputs either to a script via a pipe or to
a program via dlfunc that makes a connection to greylistd to make a whitelist
entry.
Realistically I'd like to find a way to implement "whole server whitelisting"
which was brought up on this list recently. i.e. when an email is correctly
retried, a whitelist entry is made for that server or that source IP address.
Because for instance it's silly to greylist all of GMail, and doing so is just
a waste of resources on both sides -- and same with any other legitimate mail
server.
