Greetings and Salutations

Any suggestions good salutations for formal/relatively formal emails?  

I hate saying "Dear" unless I'm writing to my Grandma you know?  Especially  when you're writing to like "Filing and Collating Department."  Dear, DEAR, filing and collating department.  It sounds retarded.  I've been rotating through "sincerely" "respectfully" and "regards" for sign-offs but they all suck too.  We gotta get rid of that shiite.  Our generation should institute the "Hello" and "Thank You" for salutations, even formal.  Concurrence?
