Self-addressing envelopes? (was: Positive Spin on Snape...)

>> The argument about the letter wouldn't be all that weak 
actually...except I don't think they have a self addressing envelope 
spell.  Remember Lockhart and Harry's detention?  Lockhart had him 
addressing the letters.<<

SSSusan:
I agree.  Am I making this up, or isn't there a scene where the 
address *changes* and the recipient is moving?  [Did I dream that?]  
Similarly, we know that as the Dursleys hit the road to escape the 
Hogwarts letters in SS/PS, the addresses changed along w/ their 
destinations.  

I think there HAS to be some kind of inherent magic, otherwise mail 
could be traced [for instance, to where Sirius is in hiding].  There 
is a difference between being able to capture an arriving owl & 
confiscating his/her messages [we know this was done] and being able 
to know where an owl is going.  I just think there has to be some 
kind of super-duper self-addressing/address-altering-if-necessary 
charm in the ink or letter *or* with the owls.

With apologies for asking what's probably a silly question whilst 
away from my books.
