Hi Mo, good to see you here out of SE. 
Well, guess I was a little cryptic. The subject Kinseeker is talking mainly was his email address getting spread out all over the world as a FWD email makes it rounds. His gripe, and it is the same with me towards most of my friends and relatives is that they just add a bunch of addresses on and forward a email out.
Ok, if I consider sending a email on to people...only if it was a good joke or good info that came to me as a FWD, then what I do is one of two things:
1. Copy and paste the text to a new email, deleting all the dozens of addresses it has accumulated, address the new email to myself and BCC to the different people. BCC, as you know is 'blind carbon copy' which each person receiving the email doesn't know who else received the email. So, if they FWD the email, which 99% will do, the other email addresses are not listed, so those addreses will not get sent around the world (if others don't delete addresses). Eventually, Spammers or someone will give/sell the huge list of addresses to Spammers. I delete the email copy addressed to me when it shows up.
2. Just delete all the addresses and FWD it on, addressing the "To" to myself and the intended receipents as "BCC" (like above) without a copy/paste to a new email.
As far as 'security'...most viruses, worms, trojans, are transmitted via email, usually by opening an attachment which activates one imbedded there. Another active way is by clicking on to web a site that is suggested by the text of a email received from a stranger. Another is by clicking on to some sex/porno web sites. Also, kazza is targeted.
