Just letting everybody know that I rebuilt the machine and it all appears to be working, including email alerts (a I just got one :-))
I have no idea what the problem was, as I followed the same instructions I did last time. but as it is so straightforward to install nagios, I thought I'd simply backup my cfg files and start again! Thanks to everybody for their help ...

Short of rebuilding the server I'm not sure what to do myself! Oh damn... be careful with this sort of offer! At least chose someone with a known and confirmed name, set up a contract, get that signed by your management, so that you know whom to strangle when things go wrong :-) > As an aside I couldn't get Nagios running at first because it couldn't > write the .pid file in /var/run.

This looks like you, during testing perhaps, ran nagios as root. Some files created were left behind, still owned by root, so that Nagios can not recreate or modify them. Now, I don't know where Nagios uses temporary files, pid files, sockets for interprocess communication, or whatever, but I would start using strace now on the running nagios processes, and check the permissions of all files (and directories) Nagios accesses...
