Yes, but only if it's the very first message for the user. Afterwards  
even if user expunges all the messages, there are two things that  
prevent this from being possible: index files and the UW-IMAP style  
"FOLDER INTERNAL DATA" message.

You could also prevent this completely by stripping the X-UID header  
in your SMTP server or LDA. For example Dovecot LDA strips all the  
Dovecot's internal metadata headers.

I guess the UID renumbering could be done some day, but for now I  
think it's just way too much trouble with not that much benefits.
