[Mimedefang] local socket name /var/spool/MIMEDefang/mimedefang.sock unsafe

[Wimprine, Thomas]

I'm having a problem with mimedefang getting this error  "local socket name
/var/spool/MIMEDefang/mimedefang.sock unsafe".
 
I checked the permissions on /var /var/spool and /var/spool/MIMEdefang, they
are all owned by defang and the process starts with no problems. However
when it tries to process a piece of mail it gives this error in the maillog
and tells the user to try again later. I'm out of ideas a the only thing I
can google is the file permission problems. 
 
Any help would be great!
Thanks
Thomas
