Es un problema de permisos del directorio del courier-authlib (authdaemon),
Leete esto, tienes tres formas de resolverlo:

####################################
 When using the standalone maildrop build with courier-authlib, one of
the following configurations must be used:

* Your mail server must invoke maildrop as the root user (the -d flag
reads the mail account's uid and gid, then drops root) .
* Manually change the permissions on the maildrop binary to be setuid root.
* Manually change the permissions on the courier-authlib's socket
directory (/usr/local/var/spool/authdaemon by default) to be globally
readable or executable.

The default permissions on courier-authlib's socket directory blocks
world-access to the filesystem socket connected to courier-authlib's
authentication daemon process. In order for maildrop to connect to the
authentication library, maildrop must either have root privileges
(which will be temporary, as soon as maildrop determines the account's
userid and groupid, it will drop root, before reading the maildroprc
file), or courier-authlib's socket directory must have world read and
execute permission.

Note that if the permissions on the socket directory are changed,
anyone on the system can connect and obtain any account's password!

It is the system administrator's responsibility to choose the
appropriate security policy when using the Courier Authentication
Library.
