Nope.

tcpserver runs as root, qmail-popup inherits root, checkpassword
inherits root but changes to the uid/gid of the user that successfully
logged in, pop3d inherits the uid/gid that checkpassword changed to.
Getting back to the very confusing question. What has procmail
setuidness got to do with pop3d?
On the permissions front you forgot to mention the owner of
$HOME/Maildir. Is it owned by the user? It should be.
Finally, if you have procmail delivering to the users $HOME/Maildir
then it does not need to be setuid root.
