[exim] whitelisting - exim and spamassassin

Hi,

Im looking at using webmin to manage my spamassassin - it allows people
to add whitelist entries into local.cf.

however, exim has a separate whitelist - local_sender_whitelist.

I thought it could be handy to have exim refer to the spamassassin
local.cf and retrieve the values from there, rather than having to
maintain two lists.

would it be possible to do this?

regards

Brian
