RT 4.2.2 - inline images are not shown in tickets

I have made a fresh install of RT 4.2.1 yesterday and noticed, that when I create a ticket using RT Web interface (rich text) and paste a screenshot or any other image to the editor, this image not being shown in either e-mail sent to requestor (tested with Outlook 2003 and Outlok 2010), or in ticket history. Outlook only shows placeholder for the image (apparently cannot decode it), and ticket history displays ‘Message body is not shown because it is too large’ (see picture below). Actua…

I’ve set MaxInlineBody to 0, reloaded the ticket and now I can see the inline image.

Update: @periway’s overlay is also needed.
