failed: Operation not permitted

I'm using vmail:vmail (5000:5000) for all my virtual users and postfix 
chrooted. I have read the wiki but I'm not using diferrent uids and gids 
for every user so, I don't understand why deliver is trying to setuid. 
sorry for my newbie question but my english is not the best and I'm 
totally lost.

any ideas?

If deliver is already running as uid 5000 (like your Postfix dovecot
line shows), this shouldn't be happening. So for some reason your
Postfix isn't calling deliver with UID 5000..
