These days, there are times when using e-mail seems far less of convenience it once was. The huge amount of spam, undeliverable mail (probalby as a result of spam), annoying Out of Office replies etc. Add to that the inherant dangers with e-mail (namely viruses) and there's no doubt we're well over our honeymoon period with e-mail.
E-mail hijacking - more correctly called spoofing - is another problem that is cropping up these days. Why? Because it's so easy to do.

And don't forget, if you're using a webmail service like Hotmail, always log-off when you finish checking your e-mail.
A good guiding principle with e-mail is: be suspicious - suspect any attachment, any request for detailed personal information, and of course suspect that $10 million inheritance from !
