In addition to spam e-mails - there are phising - a strange word for a
scam where you receive an e-mail from someone you think you know, but
in reality it's not that person or group. For instance there are many
PayPal and AOL e-mails sent that do not come from either PayPal or
AOL, but some group/person looking to steal your user ID and password.
NEVER NEVER NEVER click on any link in an e-mail for these sites, if
you need to get to the site, type the site address directly into your
web browser - www.aol.com for example. What is hidden in these e-mails
is that the www.aol.com or www.paypal.com redirect you to some other
address - so if you are suppose to be at www.paypal.com and you see
some number in the web address (for example 122.123.124.125) chances
are you're being scammed.

Yes - the e-mail from address can be faked and the web link in a
e-mail can be faked - so be careful.
