After upgrading to 7.1.1 P2 we are having an issue with messages that have external image links. Upon opening the message we get the yellow bar that says "External images are not displayed. Display Images - Always display images sent from domain.com or email@example.com".
This only occurs when using the Advanced web client with the display set as HTML in the user preferences. If I use the basic client or switch the display to Text the message opens. If I go to preferences and check the "Display pictures automatically in HTML Email" option the yellow bar disappears but I am left with only a blank message.
Does anyone have any ideas? This is happening in both Firefox 5.0.1 and IE 8.
