Courier pop3d question

Hi All,

I cant ever remember any file edits to get pop3d working.

Now I am getting refused login from the client and also an error
message in ;

/var/log/mail/info
couriertcpd: LOGIN FAILED, user=dwilson, ip=[::ffff:192.168.1.27]

and in /var/log/mail/errors ;
Aug 22 16:52:13 server couriertcpd: authdaemon: s_connect() failed: No
such file or directory
Aug 22 16:52:13 server couriertcpd: authentication error: No such file
or directory

Any help apprecaited :)
