I have run this script and then run the undo script for it and now, (I am assuming the 2 are related but perhaps not), I can't receive any incoming EMail. The mailer daemon creates the message, '550 /var/spool/mail/andy... Can't create output: Permission denied'.
 
The file has permissions -rw------. If I change the permissions, of course, to -rw-rw-rw- I can receive mail again but this means my files are world read and writable.
 
I am assuming it is this script because it asks the questions about SUID and SGID programs but I suppose it could have been something I've done. In any event has anyone any ideas.
 
TIA
