Mail::CheckUser is used to stop the mail queue filling up with 
undeliverable mail - So yes, the only place where it is sensible to 
use is when web-clients are actually submitting an email address in 
a form.

I'll have to look at the code, but it should only be used at the 
initial "enter your email address to start the registration process" 
stage.

I don't think it is a good idea to use it at the "change your 
preferences" stage as there are plenty of reasons why a perfect good 
address might temporarily become inaccessible - Validating addresses 
every time somebody clicks "save preferences" is sure to cause 
trouble sooner or later.
