This also pre-dates organized crime becoming heavily involved, and

Right. Back in the 90s spammers were trying to build their lists,
and used
fake opt outs to do so. These days through a combination of web
scraping
and dictionary attacks, they have more addresses than they know
what to do
with.
My advice to people these days is to unsub if a message is from
someone
you've corresponded with before, or if it looks like someone who is
legit
but clueless. Then hit the spam button.
My advice is to always check the full email headers for anything you
are the least bit suspicious of. Does it appear to come from whom it
purports to come from ? Is the path likely ?
(Big US companies do not as a general rule forward their
email through small Eastern European ISPs, for example.) If it fails
this test, treat it as radioactive and don't click, respond, etc.
If it passes, and if the sender is in your field, then use your
judgement. (I unsubscribe to the "newsletters" that
keep popping up from Chinese ethernet switch makers, for example.)

Of course, the browsploit issue means that clicking on ANY links in
dubious
e-mail is highly unwise.
