I am very careful:
 *  In my mail server (zimbra.free.fr) I maintain an address book I
   use only to filter received emails: all emails sent by a sender who
   is not included in the address book are sent to the trash folder. I
   regularly check this trash folder.
 *  I use POP accounts, only emails kept in the server inbox are
   downloaded in my PC.

I do understand what you mean. A parameter to enable the user to
choose as you suggest ("only display in-line images from known
contacts"), and the possibility for choosing file types to display
(images and some others types) would be very useful.
