Actually I'm trying some filters on this very matter presently.
I've been hoarding SPAM messages for about 5 years and it's reasonably true
that most (95%) of SPAM containing images has the content-type herder set
What I don't have to prove yet, whether using such a rule will trap
intended mail with images from being delivered.
From a few "genuine" messages I have received they contain a header similar:
So to be honest, filtering it to /dev/null might result in you NOT getting
mail you actually do want to get.
However, as I intend putting this into a Challenge/Response system, the
sender will be able to authorise the message through, if they aren't
already in the whitelist :)
But I'd say filtering it in your Mail Client might lead you to have to
spend hours filtering through a junkbox trying to find good mail, rather
than the other way around where your good mail stands out in it's larger
collective in your inbox.
