I'm not sure I understand your point about mailcap.  Could you
explain it a bit more?

I'd have thought disabling mailcap is less safe.  When you launch an
attachment through mailcap an attempt is made to use a safe viewer
with the safest options -- this isn't the case if you save it to disk
and launch it in a different way (command line or double-clicking).

In my experience almost all junk mail that includes pictures are
text/html, so this is something that should be configured in the HTML
renderer.
