Thanks Ged. That is helpful although for some odd reason I feel very much told off :-)
I should have added that I checked the sender domains and they all had SPF in place which is why I was tempted to try using the SPF mechanism. I have tried using hosts.deny but that doesn't seem to work for me, iptables may well be something to look at as you say. jON _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
