Automatically display images from trusted senders

[houchin]

It would be nice if RC could be set to automatically display images from "trusted sources"

Certainly, the difficult part of this is how to define a trusted source and verify that the received message is really from that source. Just looking at the "from" address is not enough. However, comparing both the "from" address and the servers listed in the received-by headers may be sufficient.

Has been implemented by from address checking in addressbook.
