I have noticed recently that some emails automatically downloaded images. When I checked the mail content exceptions in the settings I found that there were some email addresses in it that I am 99% certain I didn't manually add. I'm aware that if I click on one of the "allow remote content from..." options in the preferences dropdown in the email, that will add the address to the list of exceptions, but again I'm pretty sure I haven't done that for some of the exceptions that have appeared in the list. Is there a way that senders can somehow add themselves to the list of exceptions without my knowledge? If there is, how do I block it? Thanks, Ian
