Why are you trying to put this under /usr/local? /usr/local/var is not a
usual place to put things on Unix systems: generally speaking programs
installed under /usr/local use /var just like those installed under
/usr.

This probably shouldn't be world-readable.

Probably your Dovecot binaries are built with a default base_dir of
/var/run/dovecot. What do the following give you?

    doveconf -d base_dir        (as root)
    doveconf base_dir           (as root)
    doveconf base_dir           (as vmail:vmail)

It probably won't break anything, but why don't you just use
/var/run/dovecot in the first place and take that base_dir definition
out of dovecot.conf?
