Message from Martin Thompson

I would like to sort a huge amount of incoming mail messages according to 
country
of origin. I intend to have the 'senders' include a line similar to

Country: Canada

or 

Country: Zambia

How would I sort on this field in the BODY of a message and save to
appropriately named country folders if I do not know what countries
to expect?


ie. the above should go into 

IN.Canada

and 

IN.Zambia

Any ideas or tricks???
