Sorry, how do I check that?  My name servers as listed are 212.67.96.129 & 130.

No. It tries and then hangs.

I actually turned off my firewall through YAST, the interface provided
by SuSE, but have now turned the rules off again as suggested by Todd
Lyons through 
  iptables -F
  iptables -P INPUT ACCEPT
  iptables -P OUTPUT ACCEPT
(how do I reverse this I wonder?)
I then get: 
Chain INPUT (policy DROP)

I did some further research in the archives again last night and see
that the problem did indeed come up before and that the solution for one
person was to enable logging in clamav.conf but this didn't work for me.
I have also been trying to think hard about what I might have done to
have caused the problem.  I am not a tinkerer and the only thing I can
think of is that I installed Ximian Evolution as a mail program instead
of Kmail which does not allow connection of two ISPs.  I don't see how
that could have any effect and I don't want to remove it at this stage
as I would be in danger of losing all my mail.  Many thanks again for
your patience.  Please say so if you think we have gone far enough.
