I want to block/allow external images based on the domain of the image 
URL (since email sender domains are easily spoofed). Can I do that 
somehow?

In other words, if an email (from anyone) contains IMG tags referencing 
http://good.tld/foo.png and http://bad.tld/bar.png, is there a way I can 
instruct MailMate to load foo.png and block bar.png?

Thanks!
