[P1] Email name

I use .Mac, and am getting the odd bit of spam coming through. My e-mail
program is Entourage. Sometimes I'll accidentally click on the wrong email
subject title after clicking the 'send/receive' button and get the spam
message. Does this then send an automatic message to the spammer to tell
them my address is active?

I'm just curious as to how it works, I get about 10 spam messages a week on
.Mac
