Subject: Trojan Horse for Mac OS X

Judging from the number of people who use those mail clients and still
manage to infect themselves with whatever email worm du jour, I'd guess
quite a few. :-)

I try never to underestimate the end user. I don't know how many times I've
looked at someone's 'allowed' list on a permission-based firewall and found
various spyware and Trojans sitting there with full rights. And the
attachment feature in Outlook and OE is just buggy enough to cause lots of
folks to disable it, just to view (for example) a perfectly benign pdf. Once
it's been disabled, it's relatively easy to forget to go back and enable it.

You might have noticed I said "by default". How many people do you really
think change
that setting. Seriously.

Check out Tools, Options, Security, Do not allow executable attachments...

Uncheck it. Voila. Still there. Not removed. Just suppressed. And under
complete end
user control.

Actually, Outlook Express and Outlook will (by default) strip all executable
attachments
before you even get them. They've done this for some time.
