[MlMt] blocking external images on messages moved out of junk folder

[Eric Sharakan]

Hi, I marked a message that was placed in my junk folder (SpamSieve 
score of 73) as not junk.  It was moved to the appropriate inbox, but 
when I went to read it there, it had the banner saying it had blocked 3 
external references.  It also said the message was marked as not junk.  
I was surprised to see that banner.

I switched mailboxes and then when I went back to look at the message a 
few minutes later, the banner was gone and the message displayed 
normally.
