However, an MTA has to lookup recipients. The semantical content seems 
a good candidate for queries. A normalizing function would be handy in 
case that kind of addresses ever takes root.

Agreed. Correspondingly, it is the account lookup plugin that might 
require similar processing, rather than the MTA software proper. That 
way there's no risk to do it twice.

Is there a repository where one can browse for a C function and/or the 
test suite that you've been discussing about? Any pointer?
