[Evolution] Where the remote content "allow " lists are saved?

[Paulo Cesar Costa <paulo costafamily org>]

All:

Is there a way of manually copying and/or synchronizing the "Allow for
sites" and the "Allow for senders" lists that control whether or not
remote content from the internet in messages? 
(cf. Preferences->Mail Preferences->HTML Messages:Loading Remote
Content)

Context:
I have four different installations of evolution, one in my main
computer, and the other three in different laptops (work, development,
and portable). All have the default option of "Never load remote
content from the internet" set, so each has its own lists of allowed
sites and allowed senders. 
I would like to have them synchronized so I do not have to keep
authorizing sites and senders for each and every evolution instance
separately.
This would be also handy for new installations, so one would be able to
migrate that list.

I was not able to figure out where these lists are saved.

Thanks,
Paulo
