The answer depends very highly on how you associate their email
address with their storage.  If it's done through the standard
qmail-getpw, which checks /etc/passwd, that code checks to see if the
user owns their own homedir.  If the homedir is inaccessible, you're
hosed; the mail bounces.  If it's done through a replacement
qmail-getpw, then you could simply have the replacement code exit with 
111 if their storage was being worked on.

Don't worry about that, because the mail has already been accepted,
and is sitting in the queue.
