It lists the queued mail, and also under the sender/receiver colum 
states the problem

I did have a go at doing an 'apt-get install bind9' but it came up with 
some umnet dependencies, so I got scared off !
(I seem to remember having soem problems installing the last 
MailScanner, and did put in a lot of  CPAN stuff for perl)

I changed the /etc/resolv.conf as per Colm's suggestion, but still no 
joy, so I changed the nameserver to an external one, and all went fine.
I assume its some problem with my local caching dns server on the woody box.

started to snip away a lot, but then it looked like garabage without the 
pprevious bits !
