Much more than WMF files can be embedded and many can be dangerous.
Of course, I was only providing one example. It even branches to non-image objects contained in the e-mail.

Also, as dlishguy pointed out, sometimes the less obvious subjects HAVE to be opened if you are using business email.

It's fine to preach, just be sure you understand WHAT you are preaching. Hell, even webmail applications will often not show embedded objects or HTML images FOR THAT VERY REASON.
Exactly per webmail safeguards [some people find this annoying though and disable it]. When I said hotlinked images are not attachments - this is true in webmail. Take Hotmail for example, there is no paper clip indicating an attachment when you hotlink images [amongst other things hidden in HTML coding]. Therefore making the email seem less harmful than it could potentially be.

I agree, the ignorance is getting annoying. Email is easily the #1 form of communication in today's world for many people. It's not always easy to say for sure that something is bad. Hell, many viruses spread via attachments sent to you by people YOU KNOW. So you can't use the rule "If you don't know the sender, don't open it" because that doesn't assure your safety either. So what then? Never open ANY email? Again, be VERY careful with attachments, make sure embedded files do not show in your preview pane (easy to configure, default in many cases nowadays).
Thanks for agreeing. And you did recommend that rule, as I'm sure you're aware. But I don't advocate that rule for the very reason you said. I was operating on the more easily pre-conceived notion of "SPAM". Specifically judging from the horribly, fake looking domains in the sender's email (best defense so far that should be adopted by ALL web e-mail: Gmail's mouseover sender name w/o opening email), if there isn't a falsified 1st & last name to obscure it (you're forced to open it to learn), and by looking at the 95% of time ridiculously named subject lines - they are very easy to spot.

Understandably, you say spam is disguised as coming from contacts. But even then the subject titles ["family photos" opposed to "nude girls" is obviously going to trick you] should alert you or at least make you privvy to a behavior not of your comrades, unless you frequently exchange photos of yourselves and the like then you're doomed. Much less, ALL attachments are scanned by major web-based clients nowadays. Yet the problem is this isn't always fullproof b/c they're usually brand new viruses exploiting brand new flaws in the application [most commonly IE].

I'm not saying "Never open ANY email". NEVER open ANY suspicious email. Period. Use your common sense.

As a side note, I want to explain my qualifications in this matter ... I am a Security Services Manager for a security services firm. 50+ hours per week are spent by me protecting my clients from malware, spam, viruses, botnets and other nasties and the miscreants behind them. I do this for small, medium and large (national/global) companies. I agree with what oldtimer is saying... you don't KNOW what it is... that's why you should ALWAYS use a plaintext-only preview pane...
By all means, toot it! I love the work people in your field do and appreciate it day in and day out. But I've personally dealt with these demons myself and heavily immersed myself in this area. If I'm guilty of anything, it is for lack of detail [I didn't want to nerd out anybody] and more robust compilings making for a good example [I was pressed for time]. But again, I was never debating this in OE or any email client specifically. But web e-mail opened in a browser.

Lastly, not everybody's computer has the same level of protection as we would deem "acceptable" - people on old OS'es, lack of Windows Updates, zero anti-virus, Active X enabled, Java enabled, VBScript enabled, etc. That's why it's best to teach people to avoid reading that particular questionable e-mail [staying in webmail now] altogether. Just sayin'. Hopefully it will teach that rare innocent sender to revise his e-mail habits.
