Does that protect me from the issues being discussed?
It should ... although keep in mind that the most dangerous email
viruses use spoofed email addresses, so it might be dangerous even if
it's from someone you know.
Agreed that it "should".
Anybody else remember the old "ANSI bombs" based on ANSI.sys? Mostly effective
only against DOS users, IIRC; but I've _never_ felt comfortable about the
concept. Those who use such things are clever. I haven't heard of new
vulnerabilities along those lines since WinNT got going well with proper
configurations, but new variants on old techniques always seem to crop up.
(Had some real fun with those way back when.)
Text-only views are useful layers of defense. But you can't expect guarantees
to be worth much more than just a bunch of words in these things.
