Centralized whitelist would be a nice feature. I see two ways of
implementing that in milte-rgreylist:

1) URL inclusion: you'd say in greylist.conf that you want to include
config from an URL, with a refresh time:
include http://www.example.net/whitelist.txt refresh 1d

2) DNS based: you'd tell in greylist.conf that hosts in a given DNS
revserse list should be whitelisted.

acl whitelist dnsrbl whitelist.example.com

3) Don't add any code to milter-greylist, and have a cron launched
shell-script that fetches Joseph's file and rebuild a config file from
it. 

Solution 1 would require linking with libcurl. It would have other
advantages than centralized whitelisting: centralized configuration for
MX pools. But that can also be done externally by a cron task that just
load the file with wget or ftp and overwrite the config file. I'm not
sure it's worth implenting it. OTOH inclusion of local files is usefull
too.

Solution 2 is nice because it can also be used for greylisting hosts
that appear in various DNSRBL (dial-up DNSRBL for instance). 

Of course both can be done. As usual, IMO that's good features, but
that's not features I need, so if someone wants to work on it,
contributions are welcome.
