I'd like to add a few more email pet peves to my rant...

First, check where you are sending mail. In Outlook you hit Ctrl-K and it resolves the names - make sure they are right.

Two, limit the number of people on a mail thread to the people that care. Don't CC a mailing list of 1000 people

Third, and most importantly, never respond to a large mailing list with "Me too" when someone asks you to be removed from it.

Why can't smart people figure out these basics?
