Ten years ago, the very idea of an "email virus" was
considered laughable. Today, Outlook is one of the
primary distribution vectors for viruses.

Not with any authority, since I'm not familiar with the details
of what the virus authors have been up to lately. But unless by
"social engineering" you mean "convince a substantial percentage
of Internet users to use a notoriously insecure program as their
mail reader," then yes, that's precisely what I claim.

I wouldn't go that far, but MUAs should definitely *not*
automatically invoke executable programs from untrusted sources.
Not in today's hostile Internet, not in yesterday's more
benign Internet, not even in the trusting environment of
yesteryear's ARPANET and UUCP-based networks. *Everybody*
knows this, or at least everybody ought to.
Word documents and Excel spreadsheets, by virtue of scriptability,
are in effect executable programs. Until very recently they
didn't even have a sandbox mode to restrict what macros could do.
Like I said earlier, Word and Excel and the like are the real
culprits, not Outlook, but the fact that Outlook would automatically
fire these programs up and feed them untrusted data makes it
culpable.
