Sorry to confuse Nick, I think I may have misinterpreted your question, 
"Is the host www an internal system?" to imply that the system was 
called 'www' due to a nisconfiguration. The logs are from the mailserver 
referenced above, the intimate details of which I have appended here [1].

Previously yes, I used imap and the mail was stored on the server.
Latterly though I have changed the hardware, and for the period that the 
server was being rebuilt on new hardware I pushed the mail back to my 
isp, Andrews and Arnold, and currently bring it in from their pop3 
server. I am trying to iron out the wrinkles on this system before I 
switch back.

myhostname = mail.funkygibbins.me.uk
myorigin = /etc/mailname ['cat /etc/mailname' returns 
mail.funkygibbins.me.uk]
mydestination =

Non-authoritative answer:
Name:   mail.funkygibbins.me.uk
Address: 81.2.99.91
Pinging mail.funkygibbins.me.uk from the internal network goes to 
192.168.1.40 due to an entry in /etc/hosts.
