"Images that have URLs matching this regexp will be blocked.
Note that the main reason external images are included in HTML
emails (these days) is to allow tracking whether you've read the
email message or not. If you allow loading images in HTML
emails, you give up privacy.
The default value of this variable blocks loading external
resources when reading email groups (and therefore stops

called with the group name as the parameter, and should return a
regexp."
