[Dovecot] auth-master: Permission denied [sigh]

[James Butler]

I have changed /usr/local/libexec/dovecot/deliver permissions as follows:

-rwsr-s--- 1 root dovecot 4044835 2009-04-03 13:52 deliver

Because of message returned to 'sender at example-send.com':

"local configuration error. Command output:
/usr/local/libexec/dovecot/deliver must not be both world-executable and
setuid-root. This allows root exploits. See [LDA#multipleuids wiki page]."

Same auth-master "Permission denied" error.

Thanks again.

James
