[Dovecot] localhost deliver(root at vlocalhost): setgid(5001) failed with euid=8, gid=8, egid=8: Operation not permitted

[Alexander Prinsier]

I meant _setuid_ root, not owner root. You better lookup what this means
on google before doing it.

Reread the instructions on http://wiki.dovecot.org/LDA (section Multiple
UIDs). Set the group of the directory deliver is in to the same user
that postfix will use to run deliver. (You appear to be using 'mail').

See the manual page of chmod to know how to set a program setuid root.
